    摘要： An object is to provide a PTC element capable of preventing lead terminals from delaminating from an element body. This PTC element 1 is a PTC element comprising an element body 10 in which an electroconductive filler is dispersed in a crystalline polymer, and a pair of terminal electrodes 12, 14 thermocompression-bonded with the element body 10 in between, wherein each of the pair of terminal electrodes 12, 14 has an overlapping region 121, 141 overlapping with the element body 10, and a nonoverlapping region 122, 142 not overlapping with the element body 10, and wherein the nonoverlapping region 122, 142 of each of the pair of terminal electrodes 12, 14 is constructed of a succession of a wide portion 122a a width of which is large across a direction in which the terminal electrode 12, 14 extends from the element body 10, and a narrow portion 122b a width of which is smaller than the width of the wide portion 122a.

    摘要： 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 4.0×10−5 to 6.0×10−5 Wb·m·kg−1 when a magnetic field of 3.98×105 A·m−1 is applied to the thermistor body.
