Abstract
A temperature sensor which can be used at ordinary temperatures is provided. After a lamination plate of a phenol resin is carbonized at 640 to 750.degree. C., the powder of the carbonized material and the binder formed of a thermosetting resin, such as phenol or epoxy, are kneaded and formed into a paste, after which this paste is printed between terminals of a base film, such as polyimide, having a high resistance to heat and is calcined at a low temperature. Thus, a temperature sensor such that a resistance element is printed on the base film is obtained. The temperature sensor shows a large change of the resistance value with respect to an environment temperature change at ordinary temperatures.
