Provided is a temperature compensating circuit, which conducts a temperature correction having a continuous characteristic, and is small in the circuit scale. An output voltage VOUT at a connection point 14 is determined on the basis of a current Ia2, a current Ib2, and a current Ic2, and an output voltage of a temperature sensor circuit is corrected by the output voltage VOUT with a temperature. As a result, the temperature correction having the continuous characteristic is conducted on the basis of a current change of the current Ia2, the current Ib2, and the current Ic2. Because the plural temperature compensating circuits are not provided, and only one temperature compensating circuit is provided, the circuit scale becomes smaller.
