Abstract: An electronic device includes a transmission line and a circuit board. The transmission line includes a signal conductor, a base material, a first external connection conductor, a second external connection conductor, and a ground conductor, and defines a stripline. The circuit board includes a first mounting land conductor, a second mounting land conductor, and a radiation reduction conductor. The first mounting land conductor and the second mounting land conductor are provided in a concave portion on the surface of the circuit board, and are respectively connected to the first external connection conductor and the second external connection conductor. The radiation reduction conductor is provided on the lateral surface of the concave portion in which the transmission line is disposed, and is in contact with or adjacent to the first lateral surface and the second lateral surface of the base material.

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 of6 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.

Abstract translation: 高频信号传输线包括具有多个绝缘层的柔性主体。 线性信号线位于身体中或身上。 第一接地导体经由至少一个绝缘层位于与信号线相对的位置。 第二个接地导体沿信号线延伸。 连接第一接地导体和第二接地导体的层间连接部分包括多个层间连接导体，其分别穿过绝缘层中的一些并彼此连接。 多个层间连接导体包括两层层间连接导体，其相对于层堆叠方向在相邻的绝缘层中被刺穿，并且当从层堆叠方向观察时具有位于不同位置的中心轴。
