Patent ID: 11532410

Abstract:
Provided is a thermistor which has a smaller change in resistance value between before and after a heat resistance test and from which a high B constant is obtained, a method for manufacturing the same, and a thermistor sensor. The thermistor is a thermistor formed on a substrate and includes: an intermediate stacked portion formed on the substrate; and a main metal nitride film layer formed of a thermistor material of a metal nitride on the intermediate stacked portion, wherein the intermediate stacked portion includes a base thermistor layer formed of a thermistor material of a metal nitride and an intermediate oxynitride layer formed on the base thermistor layer, the main metal nitride film layer is formed on the intermediate oxynitride layer, and the intermediate oxynitride layer is a metal oxynitride layer formed through oxidation of the thermistor material of the base thermistor layer immediately below the intermediate oxynitride layer.
