A temperature detection circuit has a first temperature sensor circuit that outputs a voltage having a negative temperature gradient and an absolute value and a second temperature sensor circuit that outputs a voltage having a positive temperature gradient and the same absolute value as that for the output voltage of the first temperature sensor circuit. A switch circuit conducts a switching operation in accordance with a control signal to switch between outputting the output voltage of the first temperature sensor circuit and the output voltage of the second temperature sensor circuit. A comparison circuit compares the output voltage from the first or second temperature sensor circuit with a reference voltage. A logic circuit outputs a temperature detection signal on the basis of the control signal and an output signal from the comparison circuit.
