A temperature sensor circuit whose output voltage has high precision is provided. The temperature sensor circuit includes a Darlington circuit having bipolar transistors, a constant current circuit, and a current control circuit. Emitter currents of the bipolar transistors are made equal to one another by the constant current circuit. Base currents corresponding to the emitter currents of the respective bipolar transistors are sunk by the current control circuit.
