Abstract
An electric deviceis an organic positive thermistor in which, between two plate electrodesandconstituting an electrode couple, a conductive memberis disposed in a state being in a close contact with the plate electrodesand. The conductive memberis formed of many piled up resin particles each having its surface formed with a conductive layer of a residual material (fullerene residual), which is the soot including fullerenes generated via, for example, an arc discharging method, from which at least a part of fullerenes is removed. Such conductive layers are joined to each other to structure the conductive path and the conduction of the electric deviceis ensured in a normal state. When an inrush current flows, the conductive path is readily shut off by a small inflation of the resin particles due to the temperature rise.
