PROBLEM TO BE SOLVED: To solve problems that the circuit scale gets large and that electric power consumption increases, because a complicated correction circuit is required to be added in an output part or the like to compensate fluctuation of a bias voltage or the like, in a conventional multiplier using an MOS transistor. SOLUTION: This multiplier has NMOS transistors 3, 4, 5, and constant- voltage sources 6, 9, 12 connected respectively to gates of the NMOS transistors 3, 4, 5. In the multiplier, a voltage value in the constant-voltage source 9 is made equal to a voltage value in the constant-voltage source 12, and the NMOS transistor 4 and the NMOS transistor 5 are formed to be mutually the same.
