THERMISTOR SINTERED BODY AND TEMPERATURE SENSOR ELEMENT

TAKEUCHI AKITAKA / NIIZEKI NAOHIRO

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 Y2O3 phase as a main phase; and a Y(Cr/Mn)O3 phase 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)O3 phase or a YCrO3 phase, and Pr is dissolved in the Y(Cr,Mn)O3 phase or the YCrO3 phase.
