PURPOSE: To provide a thermistor type temperature sensor which can detect temperatures with high accuracy by providing a constitution which can adjust the output of the sensor.

CONSTITUTION: In a thermistor type temperature sensor, a detection resistor 2 the resistance value of which changes in accordance with temperatures and which is composed of a thermistor and an output detecting resistor 3 are integrally arranged in series on the same substrate and, when trimming adjustment is performing on the resistance value of the resistor 3 in accordance with the actual resistance value of the detection resistor 2, a thermistor type temperature sensor which can detect temperatures with high accuracy can be obtained.
