Abstract
A differential transmission line that has three or more signal lines and with which there is little unwanted radiation noise is provided. The differential transmission lineis provided with three signal lines, andthat transmit differential signals from a differential driver ICto a differential receiver IC, and the majority of the signal lines, andis provided in conductor layers Tand Tof a printed circuit board. The signal lines, andare provided with a signal line parallel segment, a signal line route length adjustment segment that is on the differential driver ICside and that connects from differential signal output terminalsEa,Eb, andEc in the differential driver ICto the signal line parallel segment, and a signal line route length adjustment segment that is on the differential receiver ICside and that connects from the signal line parallel segment to differential signal input terminals in the differential receiver IC, wherein the signal lines, andare formed such that their signal line route length adjustment segments on the differential driver ICside are equal in length to one another.
