金属箔とが別体であるため工事が難しかつた。 In general, a planar heating element includes a heating element body made of an electric resistor mounted on a substrate and an exterior material attached to the heating element body. In the conventional technology, grounding is accomplished by placing a grounding metal foil on the bottom surface of the heating element body when installing a sheet heating element, and bringing a grounding body such as a wire mesh or metal plate to which a grounding wire is attached to the grounding metal foil into overlapping contact with the grounding metal foil. It was being held. but,
In this conventional technology, the connection between the grounding metal foil and the grounding wire is insufficient, and if a foreign metal object such as a needle pierces the heating element, this foreign object will destroy the heating element body and will not reach the grounding metal foil. It was not possible to ground the leakage. Furthermore, construction work was difficult because the heating element body, the grounding wire, and the grounding metal foil were separate bodies.

きる実益がある。 According to the present invention, as described above, a metal foil is laminated on a plastic film that protects the heating element body, and a grounding body is inserted between the plastic film and the metal foil, so that the grounding body is integrated with the planar heating element. Since the grounding wire can be connected to the protruding part of the grounding body, it is easy to pull out the grounding wire.Furthermore, the grounding body is installed on the top of the planar heating element. Therefore, if a metal foreign object such as a needle pierces the heating element, the foreign object reaches the heating element in a grounded state before reaching the heating element, which has the practical benefit of being able to reliably ground the leakage current.
