More Information
Summary:In a PTC thermistor comprising at least a pair of electrodes 2 and 3 disposed so as to'face each other and a thermistor element disposed between the electrodes 2 and 3 and having a positive resistance-temperature characteristic, the thermistor element is a molded body constituted by a high molecular matrix, a low molecular organic compound, and conductive particles having electric conductivity, the molecular weight of the high molecular matrix is between 10,000 and 400,000, the molecular weight of the low molecular organic compound is between 100 and 3, 000, and the high molecular matrix is an olefin-type high molecular compound having a melting start temperature of between 85 and 95 DEG C.
