In order to improve heat resistance, this NTC thermistor element (1) is provided with: a substrate (2) made of a ceramic material including Mn, Ni, Fe, and Ti; and a pair of external electrodes (4a, 4b) formed on the substrate (2). If the molar amount of Mn in the substrate (2) is a [mol%] and the molar amount of Ni is b [mol%], then a+b=100, 44.90<=a<=65.27, and 34.73<=b<=55.10. Further, if the molar amount of Fe is c [mol%] and the molar amount of Ti is d [mol%], then 24.22<=c<=39.57 and 5.04<=d<=10.18 where a+b=100. |
