Abstract
A temperature sensor element includes: an element main body including a heat sensitive body including a thermistor sintered body of which the electrical characteristics change with temperature, and a pair of lead wires that is connected to the heat sensitive body through electrodes; and a protective layer that protects the heat sensitive body. The protective layer has an inner protective layer covering the heat sensitive body and an outer protective layer covering the outer side of the inner protective layer. The inner protective layer is formed of an aggregate of particles that are chemically stable with respect to the thermistor sintered body and made of non-metal.
