Abstract

The temperature sensor is provided with a pair of lead frames, a sensor portion connected to the pair of lead frames, and an insulating holding portion which is fixed to the pair of lead frames and holds the lead frames. The sensor portion is provided with an insulating film; a thin film thermistor portion formed as a pattern on the surface of the insulating film with a thermistor material; a pair of interdigitated electrodes formed as patterns having multiple comb portions and facing each other on the thin film thermistor portion; and a pair of pattern electrodes connected to the pair of interdigitated electrodes and formed as patterns on the surface of the insulating film. The pair of lead frames is extended and adhered to the surface of the insulating film disposing the thin film thermistor portion therebetween and is connected to the pair of pattern electrodes.

Dependent claims

A temperature sensor comprising:

a pair of lead frames;
a sensor portion connected to the pair of lead frames;
and
an insulating holding portion which is fixed to the pair of lead frames and holds the lead frames,
wherein the sensor portion further comprises:
an insulating film;
a thin film thermistor portion formed as a pattern on the surface of the insulating film with a thermistor material;
