Abstract:
In an interposer substrate, a plating stub conductor and a ground conductor form a capacitor, and a plating stub conductor and the ground conductor form a capacitor. Capacitances of the capacitors are adjusted so that a phase difference between signals transmitted by a differential transmission using a signal line including a connection wiring conductor and a signal line including a connection wiring conductor is equal to 180 degrees.
