PROBLEM TO BE SOLVED: To provide a differential transmission line having three or more signal lines and less unnecessary radiation noise. SOLUTION: The differential transmission circuit transmits a plurality of differential signals from a differential driver IC 1 to a differential receiver IC 3 via the differential transmission line 2 having the signal lines 2a, 2b, 2c. The differential transmission circuit is provided with a timing controller 13 which stores time difference when an optional set of differential signals of three sets of differential signals progress from output terminals 1Ea, 1Eb, 1Ec of the differential signals in the differential driver IC 1 to a signal line parallel running section in which the respective sets of signal lines mutually run in parallel, and output timing adjustment circuits 12-1, 12-2 which adjust timing of a set of differential signals to be output from the differential driver IC so as to compensate time difference.
