Abstract
The present invention relates a method for manufacturing high-temperature thermistor materials having stable thermistor properties and to a high-temperature thermistor. According to this method the thermistor material is obtained by mixing powders of (Mn.Cr) O.sub.4 spinel powder and Y.sub.2 O.sub.3 powder and firing the mixed powder at a temperature in a range of 1400.degree. to 1700.degree. C., so as to cause the components of the mixture to react with each other, thereby generating (Mn.sub.x.Cr.sub.y) O.sub.4 spinel and Y(Cr.Mn) O.sub.3 perovskite.
