PROBLEM TO BE SOLVED: To provide a temperature sensor which gives high positional accuracy and has excellent responsiveness upon detecting temperature by pressing the sensor to a heating roller or the like.SOLUTION: The temperature sensor comprises: a pair of lead frames 2; a sensor part 3; and an insulating holding part 4. The sensor part includes an insulating film 6, a thin film thermistor part 7 formed on the insulating film, a pair of interdigital electrodes 8 having a plurality of comb-shaped parts formed on the thin film thermistor part, and a pair of pattern electrodes 9 formed on the insulating film. The pair of lead frames includes a pair of through-holes 2a in a middle part thereof. The insulating film has a pair of film-side protrusions 6b protruding from an end side. While the pair of film-side protrusions is inserted up to the end side into the pair of through-holes, the pair of lead frames is extended as interposing the thin film thermistor part therebetween and fixed to the insulating film, and is connected to the pair of pattern electrodes. |
