THERMISTOR SINTERED BODY AND TEMPERATURE SENSOR ELEMENT
[Problem] To provide a thermistor sintered body and a temperature sensor element such that a resistance value can be adjusted in a wider range while minimizing the effect on a B constant. [Solution] This thermistor sintered body comprises a sintered body which includes a Y2O3 phase as a main phase and a Y(Cr/Mn)O3 phase as a subphase. The chemical composition of Cr, Mn, Ca, Pr, and Y excluding oxygen comprises one or both of Cr: 20 mol% or less and Mn: 20 mol% or less, Ca: 1 to 15 mol%, and Pr: 0.5 to 30 mol%, the balance being unavoidable impurities and Y. In the present invention, preferably, the subphase is a Y(Cr,Mn)O3 phase or a YCrO3 phase, and Pr is soluble in the Y(Cr,Mn)O3 phase or the YCrO3 phase.
