PROBLEM TO BE SOLVED: To provide the organic positive temperature coefficient thermistor which has a sufficiently low room-temperature resistance, a large resistance variation rate between an operating state and a nonoperating state, small hysteresis of the temperature-resistance curve, its operation temperature easily adjusted, and high characteristic stability. SOLUTION: The organic positive temperature coefficient thermistor includes at least two kinds of high-molecular weight matrix, a low-molecular weight organic compound, and conductive particles having spike-shaped projections. As the high-molecular weight matrixes, at least two kinds of thermoplastic high-molecular weight matrix having different fusion points or at least one kind of thermoplastic high-molecular weight matrix and at least one kind of thermosetting high-molecular weight matrix are used.
