PROBLEM TO BE SOLVED: To provide a technology for reducing a switching noise in the interface circuit of an information processor with redundant configuration. SOLUTION: This interface circuit of an information processor for transmitting information from a plurality of transmission side logic circuits for performing the same processing to a plurality of reception side logic circuits for performing the same processing is provided with a first transmission system for transmitting a first signal through a first signal transmission line and a second transmission system for transmitting a second signal whose logical polarity is opposite to that of the first signal through a second transmission line arranged adjacently to the first signal transmission line. The signals from the plurality of transmission side logic circuits are respectively transmitted on at least the first and the second signal transmission lines as signals whose logical polarities are opposite to each other.
