ABSTRACT:
An organic positive temperature coefficient thermistor contains polyethylene oxide where Mw>2,000,000 and conductive particles each having spiky protuberances. Preferably, the thermistor is prepared by blending the polyethylene oxide with the conductive particles interconnected in a chain form. The thermistor is operated at a temperature of 60 to 70.degree. C. little harmful to the human body, and has low initial resistance in its non-operating state (at room temperature), a large rate of resistance change upon transition from its non-operating state to operating state, a sharp resistance rise upon operation, and stable performance even upon repetitive operation.
