<P>PROBLEM TO BE SOLVED: To provide a differential transmission line capable of transmitting a high frequency signal efficiently by reducing the impact of external noise, and to provide a multilayer wiring board including the differential transmission line. <P>SOLUTION: In a differential transmission line consisting of a pair of wiring conductors having a first wiring conductor 2 and a second wiring conductor 3 facing each other vertically with an insulation layer therebetween, the end of one first wiring conductor 2a and the end of the other first wiring conductor 2b are connected electrically via a first through conductor 4 provided to penetrate the insulation layer, the end of one second wiring conductor 3a and the end of the other second wiring conductor 3b are connected electrically via a second through conductor 5 provided to penetrate the insulation layer, and a ground through conductor 6 is provided between the first through conductor 4 and the second through conductor 5. Impact of external noise is reduced, and a high frequency signal can be transmitted efficiently. <P>COPYRIGHT: (C)2013,JPO&INPIT |
