A PTC thermistor 10 comprises, at least, a pair of electrodes 2, 3 and a thermistor body 1, disposed between the electrodes 2, 3, having a positive resistance vs. temperature characteristic. The thermistor body includes, at least, a thermoplastic resin and an electrically conductive particle made of a metal powder. The thermoplastic resin and electrically conductive particle have respective contents and a state of dispersion adjusted so as to yield a magnetization of 4.0x10<-5 >to 6.0x10<-5 >Wb.m.kg<-1 >when a magnetic field of 3.98x10<5 >A.m<-1 >is applied to the thermistor body.
