Electronic components are connected to the signal transmission conductor through the connection terminals and via-hole conductors (b1, b2). It will be connected.

  The signal line member (signal line (10)) shown in Patent Document 2 includes a dielectric layer (insulator layers (22a to 22d)). In the dielectric layer, a signal transmission conductor (signal line (32)) is embedded in the dielectric layer, and the signal transmission conductor is arranged on the outer surface side of the signal transmission conductor in the dielectric layer and faces each other. It is sandwiched between a conductor (ground conductor (30)) and a ground conductor (ground conductor (34)).
