<p><P>PROBLEM TO BE SOLVED: To provide a structure capable of stably enhancing electric conductivity of an electric heating wire and solder and capable of alleviating generation of reflection light. <P>SOLUTION: The heater element consists of electric heating wires 13 and an electrode part 17, wherein the latter 17 is structured of a pair of conductive metal belt bodies 15, 16 pinching the former 13, and solder 14 filling a gap between the conductive metal belt bodies 15, 16, while each of the former 13 includes a core wire 10, a base plating layer 11 coated with the core wires 10, and a black-color plating layer 12 coating the base plating layer 11. The base plating layer exhibits coupling action coupling the core wire and the black-color plating layer. The black-color plating layer has fine wettability with the solder, that is, has solderability. As a result, electric conduction performance carried out in the order of the heating wire, the base plating layer, the black-color plating layer and the solder is good and stable. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
