ABSTRACT:
A positive-temperature-coefficient thermistor heating device including of a PTC element, a first electrode formed on its surface, a heat radiating means having heat radiating fins and a second electrode, and conductive particles contained in the first electrode and electrically conductive with the second electrode, and, also, a process for production of a positive-temperature-coefficient thermistor heating device including the steps of printing an electrode material paste containing conductive particles on the surface of a PTC element, heating this to bake it on and form a first electrode having a rough surface, and bringing the first electrode and the second electrode of the heat radiating means into contact by the conductive particles.
