PROBLEM TO BE SOLVED: To suppress electromagnetic radiation and to enhance tolerance to noise with respect to difference signal transmission. SOLUTION: With respect to difference signal transmission, a means (common mode choke coil) which suppresses a common mode current flowing to a difference signal line is incorporated in an IC on the difference signal transmission side, and a common mode noise countermeasure means (center tap terminated parts) is incorporated in an IC on the difference signal reception side, and thus the signal line length between a driver on the difference signal transmission side and the means which suppresses the common mode current or between a receiver on the difference signal reception side and the common mode noise countermeasure means is shortened.
