An element portion of a thermistor element is composed of a mixed sintered body (MM')O3.AOx of a composition of a complex perovskite oxide presented as (MM')O3, and a metallic oxide presented as AOx. In said complex perovskite oxide (MM')O3, M is at least one element selected from the elements of the groups 2A and 3A excluding La in the Periodic Table, and M' is at least one element selected from the elements of the groups 3B, 4A, 5A, 6A, 7A and 8 in the Periodic Table. Said metallic oxide AOx is a heat-resistant, metallic oxide having a melting point of 1300° C. and more, and a resistivity of AOx itself at 100° C. in the form of a thermistor element is 1000OMEGA or more. The thermistor element can realize a resistivity of 100OMEGA-100 kOMEGA, within the temperature range from room temperature to 1000° C., and small change in resistivity.
