摘要： A thermistor has a thermistor element, a protective film, and an electrode portion. The protective film is formed of a SiO2 film having a film thickness in a range of 50 nm or more and 1000 nm or less. The protective film is formed in contact with the thermistor element. Alkali metal is unevenly distributed in a region including an interface between the thermistor element and the protective film.
