Abstract
A heating element includes a base substrate, a pair of electrodes, a resistor capable of generating heat, a conductive resin, a terminal member, a hot melt adhesion metal, a hot melt cohesion metal, and a lead wire. The pair of electrodes is provided on the base substrate, and the resistor is formed between the pair of electrodes. The conductive resin is provided on each of the electrodes, and the terminal member is provided on the conductive resin. The adhesion metal is provided on the terminal member, and the cohesion metal forms a molten phase along with the adhesion metal. An end of the lead wire is welded to the cohesion metal. The conductive resin is provided in the vicinity of the adhesion metal so as to be affected by heat of the adhesion metal.
