Abstract: A multilayer substrate includes a stacked body including a first main surface, and a conductor pattern (including a mounting electrode provided on the first main surface, and a first auxiliary pattern provided on the first main surface). The stacked body includes a plurality of insulating base material layers made of a resin as a main material and stacked on one another. The first auxiliary pattern is located adjacent to or in a vicinity of the mounting electrode. The mounting electrode, in a plan view of the first main surface (when viewed in the Z-axis direction), is interposed between a different conductor pattern (the mounting electrode) and the first auxiliary pattern.

Abstract: An electric element includes a substrate including a resin layer and a first conductive body, and a magnet. The substrate includes a first principal surface facing the magnet. The first conductive body includes a coil portion having a winding axis orthogonal to the first principal surface and located on a side closest to the first principal surface. The coil portion includes a continuous coil conductor including a first coil surface facing the first principal surface and a second coil surface opposite to the first coil surface. The coil conductor has a non-uniform thickness in a winding axis direction varying a distance between the first and second coil surfaces, and a difference of maximum and minimum values of distance between the first coil surface and the first principal surface is smaller than a difference of maximum and minimum values of distance between the second coil surface and the first principal surface.

Abstract: A multilayer substrate includes a stacked body of insulating base material layers and conductor patterns on the insulating base material layers. A thickness adjustment base material layer includes a frame portion, an opening portion inside the frame portion, and an island shaped portion inside the frame portion, and connection portions to connect the island shaped portion to the frame portion. The conductor patterns, in a stacking direction of the insulating base material layers, are wound around the island shaped portion. A line width of the connection portions is smaller than the width of the island shaped portion connected to the frame portion through the connection portions. An area overlapped with the conductor patterns is larger in the opening portion than in the frame portion and the island shaped portion.

Abstract: A transmission line substrate includes a line portion, a base including a first main surface and a second main surface opposite to the first main surface, first and second ground conductors, and a signal line. The first ground conductor is on the first main surface side. The second ground conductor is on the second main surface side. The first ground conductor includes first conductor-non-formed portions overlapping the signal line when viewed in the Z axis direction. The second ground conductor includes second conductor-non-formed portions overlapping the signal line when viewed in the Z axis direction. A total area of the second conductor-non-formed portions is less than a total area of the first conductor-non-formed portions.

Abstract: A multilayer substrate includes a stacked body including a principal surface and insulating base material layers made of a thermoplastic resin that are stacked, and a coil including coil conductors. The coil includes a winding axis in a stacking direction. The coil conductors includes a first coil conductor closest to the principal surface, and a second coil conductor adjacent to or in a vicinity of the first coil conductor. The second coil conductor includes a wide portion of which a line width is larger than a line width of the first coil conductor. The wide portion includes an overlapping portion that overlaps with the first coil conductor, and a non-overlapping portion that does not overlap with the first coil conductor, when viewed from the stacking direction. The non-overlapping portion is curved to be closer to the principal surface than to the overlapping portion.

Abstract: An actuator includes a coil that provides a magnetic field to move a permanent magnet in a moving direction perpendicular to a coil axis. The coil includes conductor patterns on an insulating base material layer. The permanent magnet is located above insulating base material layer so that a polar direction of the permanent magnet is the moving direction. The conductor patterns include a closest conductor pattern closest to the permanent magnet. A first maximum width of an interval inside the closest conductor pattern in the polar direction is smaller than a second maximum width of an interval inside another conductor pattern in the polar direction. An overlapping width in the polar direction between the interval of the first maximum width inside the closest conductor pattern and the permanent magnet is the first maximum width regardless of a position of the permanent magnet.

Abstract: A multilayer substrate includes a lamination body including a first resin substrate, a second resin substrate, and a bonding layer that are hot-pressed. A first conductor pattern including a surface defined by a plated film is disposed on a first surface of the first resin substrate. A second conductor pattern including a surface defined by a plated film is disposed on a second surface of the first resin substrate. A third conductor pattern including a surface defined by a plated film is disposed on a third surface of the second resin substrate. A fourth conductor pattern including a surface defined by a plated film is disposed on a fourth surface of the second resin substrate. The first conductor pattern is located closer to one outermost layer than the second conductor pattern is. The second conductor pattern is thinner than the first conductor pattern.

Abstract: A laminate of a laminated coil includes first and second sections in a stacking direction from a first surface toward a second surface. The number of windings of each of coil conductor patterns on insulation resin layers, respectively, in the first region is equal to or more than the number of windings of a coil conductor pattern on an insulation resin layer in the second section, and is more than the number of windings of the coil conductor pattern closest to the second surface in the second section. The number of main conductor portions per unit distance in the first section is more than the number of main conductor portions per unit distance in the second section. The outermost main conductor portion of the coil conductor pattern in the second section has a width more than a width of the main conductor portion of the coil conductor pattern in the first section.

Abstract: A method for manufacturing a multilayer coil includes preparing a first substrate by forming a first conductor pattern on a first insulating base material layer, preparing a second substrate by forming a second conductor pattern on a second insulating base material layer, and joining a surface of the first substrate on which the first conductor pattern is formed and a surface of the second substrate on which the second conductor pattern is formed together with only a joining layer made of a thermoplastic resin interposed therebetween. Amounts of deformation of the first and second insulating base material layers are less than that of the joining layer at a fusion temperature. The first and second conductor patterns are each a coil pattern having a coil axis that extends in a lamination direction in which the first substrate and the second substrate are laminated together.

Abstract: A multilayer substrate includes a stacked body, coil conductor patterns, and a connection conductor pattern. The stacked body includes insulating layers. A first coil conductor pattern is provided on the front surface of an insulating layer and has a wound shape including outer and inner end portions. A second coil conductor pattern is provided on the front surface of the insulating layer and includes an end portion. The connection conductor pattern is provided in the stacked body, and connects the coil conductor patterns. The outer end portion is connected to a terminal conductor on a back surface of the stacked body. The end portion of the second coil conductor pattern is connected to the terminal conductor on the back surface of the stacked body. The first coil conductor pattern extends parallel or substantially parallel to the second coil conductor pattern along an outer periphery of the second coil conductor pattern.
