Abstract:
1. A heating element, comprising: a base substrate; a pair of electrodes formed on the base substrate; a resistor formed between the pair of electrodes and capable of generating heat; a conductive resin formed on each of the electrodes and including a thermosetting material; a terminal member formed on the conductive resin; a hot melt adhesion metal formed on the terminal member; a hot melt cohesion metal forming a molten phase along with the adhesion metal; a lead wire having an end to which the cohesion metal is bonded by hot-melting, and an armoring member covering the pair of electrodes, the resistor, the terminal member, and the adhesion metal, the armoring member being provided with a through hole, wherein the conductive resin is formed in the vicinity of the adhesion metal so that the conductive resin is affected by heat of the adhesion metal and the cohesion metal; the molten phase is formed via the through hole and between the cohesion metal and the adhesion metal; and each of the electrodes includes resin and conductive powder dispersed in the resin.
