Abstract
In a temperature sensor having a temperature sensitive element, a sheath pin connected to the temperature sensitive element, and a cover case. The cover case, filled with a filler, accommodates the temperature sensitive element and the sheath pin. A hardening temperature of the filler is not less than an actual usage environment of the temperature sensor. Another temperature sensor has a temperature sensitive element exposed at a high temperature of not less than 750° C., a thermistor element, a sheath pin, an anti-vibration filler, and a metal cover case fixed to an end part of the sheath pin. The metal cover case accommodates the sheath pin and the thermistor element. The filler is made of a porous insulation material having a pore ratio within a range of 30 to 70% and filled around the thermistor element in the metal cover case.
