摘要： A thin film thermistor element 10 is formed by forming on a backing substrate 11 of alumina a thermistor thin film 12 and a pair of comb electrodes 13 and 14 formed of a thin film of Pt. The thermistor thin film 12, which is formed of, for example, complex oxide of Mn—Co—Ni, has either a spinel type crystal structure which is priority oriented or oriented mainly in a (100) surface or a bixbite type crystal structure which is priority oriented in a (100) or (111) surface. Alternatively, the thermistor thin film is formed of LaCoO3 and has a rhombohedral bixbite type crystal structure. This makes it possible to hold the variation in resistance value low thereby to achieve high accuracy, and the deterioration with time can be held low and the high temperature durability can be improved, for the achievement of high reliability.
