The thermistor element of the present invention is composed of a mixed sintered body aM1M2O3.bY2O3 of a composition M1M2O3 (wherein M1 is Y, and M2 is at least one element selected from the elements such as Cr, Mn, Ti, etc.) as a perovskite compound and Y2O3, wherein molar fractions a and b satisfy the relations 0.05<=a<1.0, 0<b<=0.95 and a+b=1. Another wide-range type thermistor element of the present invention is composed of a perovskite compound M1(M2M3)O3, wherein M1 is at least one element selected from the elements of the groups II and IIIA excluding La in the Periodic Table, and each of M2 and M3 is at least one element selected from the elements of the groups IIB, IIIB, IVA, VA, VIA, VIIA and VIII. a and b satisfy the relations a+b=1 and 0<b<0.1, where a is a molar fraction of M2 and b is a molar fraction of M3 in M1(M2M3)O3.
