Abstract
In order to present a temperature sensor which works stable also in a high temperature condition showing only a small deviation in the resistance value of thermistor, the invented temperature sensor comprises a heat resisting cap (5) made of a metal, a thermistor (1) housed inside the heat resisting cap (5) and at least more than one lead wire (4) which is electrically connected with the thermistor (1) and is pulled out of said heat resisting cap (5), said heat resisting cap (5) being formed with an alloy containing Ni--Cr as the main ingredient.
