Abstract: A signal transmission line includes first and second base materials, and conductive bonding materials. The first base material includes a signal conductor. The second base material includes a ground conductor. The conductive bonding materials bond the first base and second base material to provide a gap. The first base material includes a mounting conductor to which the conductive bonding materials are respectively bonded. The mounting conductor includes a portion extending in parallel or substantially in parallel with the signal conductor on a side of a first side surface, and a portion extending in parallel or substantially in parallel with the signal conductor on a side of a second side surface. A position of a portion of the mounting conductor on the side of the first side surface and a position of a portion of the mounting conductor on the side of the second side surface are different from each other in a signal transmission direction.

Abstract: A signal transmission line includes a laminate, a signal conductor, a hollow portion, and a reinforcing conductor. The laminate includes a flexible laminate including resin layers each of which has flexibility. The signal conductor extends in a signal transmission direction of the laminate and is disposed in an intermediate position in a laminating direction of the resin layers. The hollow portion is in the laminate and defined by an opening provided at a portion of the plurality of resin layers. The reinforcing conductor is in the laminate. The hollow portion is disposed at a position overlapping with the signal conductor, in a plan view of the laminate from a surface perpendicular or substantially perpendicular to the laminating direction. The reinforcing conductor is disposed at a position different from the position of the hollow portion in a plan view.

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 high-frequency signal transmission line includes a flexible body including a plurality of insulating layers. A linear signal line is located in or on the body. A first ground conductor is located opposite to the signal line via at least one of the insulating layers. A second ground conductor extends along the signal line. An interlayer connection portion that connects the first ground conductor and the second ground conductor includes a plurality of interlayer connection conductors individually pierced in some of the insulating layers and connected to each other. The plurality of interlayer connection conductors includes two interlayer connection conductors that are pierced in adjacent ones of the insulating layers with respect to a layer-stacking direction and that have central axes located in different positions when viewed from the layer-stacking direction.
