Claims

[Claims for Utility Model Registration] A metal having a plate-shaped metal core, a through hole into which a lead wire of a heating element provided in the metal core is inserted, and an insulating layer insulating the surface of the plate-shaped metal core. In the core substrate, a counterbore hole corresponding to the shape of the heating element is provided in the insulating layer on the surface on which the heating element is mounted, and a highly thermally conductive insulating sheet is placed such that the upper surface thereof is in contact with the bottom surface of the heating element and the lower surface is in contact with the bottom surface of the heating element. is closely inserted into the counterbore hole so as to contact the metal core.
