PROBLEM TO BE SOLVED: To provide a mean value circuit capable of outputting a desired value, namely, a mean value of input voltages with a sufficiently high precision. SOLUTION: A mean value circuit 1 is provided with a first input terminal 10a, a second input terminal 10b, a third input terminal 10c, a processing circuit part 20, and an output terminal 30. The processing circuit part 20 comprises operational amplifiers 22a, 22b, 22c, and 24 provided in paths from input terminals 10a, 10b, and 10c to the output terminal 30 and processes input voltages V<SB>x</SB>, V<SB>y</SB>, and V<SB>z</SB>inputted from input terminals 10a, 10b, and 10c respectively to generate a voltage corresponding to a mean value of these input voltages.
