PCT No. PCT/JP97/03271 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Sep. 16, 1997 PCT Pub. No. WO98/12714 PCT Pub. Date Mar. 26, 1998Provided are wide-range thermistor materials with high responsibility, which have linear resistance temperature characteristics and a large rate of temperature-dependent resistance change in wide temperature range of from lower than room temperature to higher than 1000 DEG C. The thermistor material comprises an electrically-insulating ceramic matrix and second phase grains as discontinuously dispersed in the matrix, in which the second phase grains are of a semiconductive or conductive substance having a large rate of temperature-dependent resistance chance. The material may optionally contain a resistance-controlling additive of one or more of nitrides, borides, silicides, sulfides, oxides and carbide of elements, third phase grains with internal stress-relaxing ability having a lower modulus of elasticity than the matrix and the second phase grains, and a resistance stabilizer of TiO2 and/or TinO2n-1 (n=4 to 9).
