PURPOSE:To obtain a thermistor having desired thermistor characteristics and a desired shape, by making the following conjugate: Mn-Ni-Cr system oxide semiconductor whose main component is Mn, and ZrO2 and HfO2 being high resistivity oxide. CONSTITUTION:Mn-Ni-Cr system oxide semiconductor A whose main component is Mn, and ZrO2 and HfO2 being high resistivity oxide are made conjugate. When the composition of the semiconductor A is set as 100 atomic% in all, zirconium of 0.1-24.9 atomic% and hafnium of 0.1-24.9 atomic%, whose sum is 5-25 atomic%, are contained. Then a constant B is kept nearly constant, and only resistivity is changed. Thereby, a thermistor element having. desired thermistor characteristics and a desired shape is obtained.
