To provide a positive temperature coefficient heating element having good heat dissipation efficiency which generates heat by energization without increasing the temperature to a predetermined temperature or higher and to supply hot air generated by using the positive temperature coefficient heating element as a heat source.

The positive temperature coefficient heating element includes: a molded resistor 11 made of a mixture of sintering materials, whose main materials are aluminum powder, graphitic powder and clay powder, which is sintered after molding the external form by compression molding or extrusion molding and forming a plurality of through holes 12; and a pair of electrodes 13 and 14 formed on the molded resistor 11. Since the molded resistor 11 has a positive resistance temperature characteristic in which the resistance is low at normal temperature and the resistance suddenly increases when the temperature rises to a predetermined level, a mixture of sintering materials made by mixing aluminum powder, graphitic powder and clay powder becomes a strong and dense state by applying pressure to the mixture of sintering materials to form. Therefore, a high-strength positive temperature coefficient heating element 10 can be obtained by sintering in this state.
