摘要： A coil component includes a main body made of a magnetic material, a linear inductor wiring conductor arranged in the main body, an electrically insulating pedestal having a top surface extending along the inductor wiring conductor in the main body and a pair of side surfaces each extending from both outer edges of the top surface in a direction intersecting the top surface, and a conductive seed layer provided over an entire region of at least a region sandwiched between the top surface of the pedestal and the inductor wiring conductor. When a width dimension of a surface of the inductor wiring conductor in contact with the seed layer is defined as a first width dimension and a width dimension of the seed layer is defined as a second width dimension, the second width dimension is larger than the first width dimension.

摘要： A coil component includes an insulating layer that has a main surface; and a circuit pattern that is embedded in the insulating layer and extends along the main surface. The circuit pattern includes a seed pattern that extends along the main surface within the circuit pattern, and in a cross section orthogonal to an extending direction of the circuit pattern, the circuit pattern has a part in which the number of seed patterns is two or more.

摘要： An inductor conductor is configured such that, with respect to a height-wise dimension of the inductor conductor between the top surface and the bottom surface thereof, the height-wise dimension of a central portion of the top surface is smaller than the height-wise dimension of an edge portion of the top surface at a cross section of the inductor conductor taken in a direction orthogonal to an extending direction of the inductor conductor.

摘要： An inductor component includes a base body, an underlying insulation layer, an inductor wiring line, and a covering insulation layer. The underlying insulation layer is within the base body, and includes a first major face. The inductor wiring line is on the first major face within the base body, and extends along the first major face. The covering insulation layer is within the base body, and covers at least part of the inductor wiring line. The inductor wiring line includes a seed layer, and a plating layer in contact with the seed layer. As seen in a first cross-section orthogonal to a direction in which the inductor wiring line extends: the inductor wiring line includes first and second leg portions and a crotch portion. The first and second leg portions are in opposite end portions of a lower face of the inductor wiring line in a width direction.

摘要： In an electronic component including a circuit pattern embedded in an insulating layer, connection reliability between the circuit pattern and a wiring conductor outside the insulating layer is improved. An electronic component includes an insulating layer; a circuit pattern embedded in the insulating layer; a wiring conductor formed outside the insulating layer; and an interlayer connection portion that connects a circuit connection portion, which is a part of the circuit pattern, and the wiring conductor with an opening of the insulating layer interposed therebetween. In the circuit pattern, a thickness of a portion immediately below the interlayer connection portion of the circuit connection portion is larger than an average thickness of a portion other than the circuit connection portion.

摘要： An inductor component capable of improving an inductance value includes an element body that includes a magnetic layer and has a first principal surface and a second principal surface opposite to each other; a coil in the element body; and an insulation layer that covers a part of an outer surface of the coil. The coil has a first inductor wire wound along a plane orthogonal to a first direction which is orthogonal to the first principal surface and is from the second principal surface toward the first principal surface. At least a part of an inner peripheral surface of an innermost periphery of the first inductor wire is in contact with the magnetic layer without being covered with the insulation layer.

摘要： An electronic component capable of improving connection reliability between a via conductor and a circuit pattern. An electronic component includes a circuit pattern; an insulating resin layer covering the circuit pattern; a via conductor provided inside the insulating resin layer and connected to the circuit pattern; and a wiring member connected to the circuit pattern via the via conductor. The via conductor and the wiring member are integrally formed, and in the via conductor, a diameter of an end portion on a side close to the circuit pattern is larger than a diameter of an end portion on a side close to the wiring member.

摘要： An inductor component includes a base body having a main surface, an inductor wiring extending in parallel to the main surface in the base body, a first vertical wiring, connected to a first end of the inductor wiring, that is exposed through the main surface, and a second vertical wiring, connected to a second end of the inductor wiring, that is exposed through the main surface. The base body has an upper magnetic layer disposed closer to the main surface than the inductor wiring. The first vertical wiring and the second vertical wiring have columnar shapes extending in a thickness direction while penetrating the upper magnetic layer. The dimension in the thickness direction of the penetration portion, which penetrates the upper magnetic layer, of the first vertical wiring is five times or more the maximum dimension in the thickness direction of the inductor wiring.
