Abstract
A thermistor sintered body and a temperature sensor element that can adjust a resistance value in a wider range while suppressing an influence on a B constant. A thermistor sintered body of the present invention includes: a YOphase as a main phase; and a Y(Cr/Mn)Ophase as a subphase, wherein a chemical composition of Cr, Mn, Ca, Pr and Y excluding oxygen includes one or two of Cr: 20 mol % or less and Mn: 20 mol % or less, Ca: 1 to 15 mol %, and Pr: 0.5 to 30 mol %, with the balance being unavoidable impurities and Y. In the present invention, preferably, the subphase is a Y(Cr,Mn)Ophase or a YCrOphase, and Pr is dissolved in the Y(Cr,Mn)Ophase or the YCrOphase.
