PROBLEM TO BE SOLVED: To provide a temperature sensor that has high accuracy and excellent responsiveness and hardly causes damage to an object to be measured, when pressing against a heating roller or the like to detect temperature.SOLUTION: A temperature sensor comprises a pair of lead frames 2, a sensor part 3 connected to the pair of lead frames, and an insulating holding part 4 for holding the lead frames. The sensor part includes: a band-like insulating film 6; a thin film thermistor part 7 pattern-formed at the central part of the surface of the insulating film; a pair of interdigital electrodes, having a plurality of interdigital parts on the thin film thermistor part, pattern-formed facing each other; and a pair of pattern electrodes 9, whose one end is connected to the pair of interdigital electrodes and whose other end is connected to the pair of lead frames at the end of the insulating film, pattern-formed on the surface of the insulating film. The insulating film has the thin film thermistor part arranged at its tip part, in a state of being bent substantially in a U shape, and has its both ends fixed to the pair of lead frames. |
