A data transmission system is provided with a transmission unit, a receiving unit, transmission paths, and a delay unit. The delay unit is disposed on a transmission path along which a high-speed signal is transmitted, and delays the transmission of the high-speed signal with respect to a low-speed signal. When the high-speed signal is transmitted from a section b2 to c along the transmission path, a delay time of Deltat occurs with respect to when the high-speed signal is transmitted from a section a to b1 along the transmission path. In other words, the phase of the high-speed signal transmitted from section b2 to c is shifted with respect to the phase of the high-speed signal transmitted from section a to b1. Consequently, a time interval in which an EMI peak value occurs can be reduced, thereby enabling the probability of an EMI peak value occurring to be reduced.
