Abstract
A temperature sensor utilizes the temperature characteristics of a resistance element to detect the temperature by sensing a change in the temperature as a change in the resistance of the resistance element. The resistance element includes a first resistance element which is arranged at such an angle that the resistance thereof increases relative to an angular change in one direction of a magnetic vector that is imparted, and a second resistance element which is arranged at such an angle that the resistance thereof decreases relative thereto. The change in the temperature is sensed as a change in the added value of resistances of the first and second resistance elements.
