PROBLEM TO BE SOLVED: To provide an inter-block transmission/reception circuit that achieves stable signal transmission by suppressing variation of a current signal caused by variation of wiring resistance in transmission of inter-block wiring on a semiconductor substrate. SOLUTION: A receiving circuit includes first and second constant current source means connected to a pair of first and second receiving terminals receiving complementary current signals, a first NMOS transistor of which a source is connected to the first receiving terminal and the first constant current source means and of which a drain is connected to a first power source via a first output terminal and a first resistance means, and a second NMOS transistor of which a source is connected to the other second receiving terminal and the second constant current source means and of which a drain is connected to the first power source via a second output terminal and a second resistance means, wherein a gate voltage of the second NMOS transistor is controlled by a voltage signal of in-phase with a voltage signal of the first output terminal and a gate voltage of the first NMOS transistor is controlled by a voltage signal of in-phase with a voltage signal of the second output terminal.
