PROBLEM TO BE SOLVED: To provide an organic PTC thermistor having a sufficiently low room temperature resistance, large resistance change ratio at the time of operation and non-operation, small hysteresis in a temperature-resistor curve, easiness in tuning of operating temperature and high property stability. SOLUTION: The organic PTC thermistor of this invention comprises at least two sorts of polymer matrices, low molecule organic compound, and conductive particles with spike-like projections. As a polymer matrix, at least two sorts of thermoplastic polymer matrices with different melting points, or at least one sort of thermoplastic polymer matrix and at least one sort of thermosetting polymer matrix are used.
