PURPOSE:To prevent an erroneous action due to static electricity charging one's body or the like from occurring by bringing a metal-film-like sheet loaded on a keyboard into contact with a back plate through an adhesive. CONSTITUTION:The aluminum sheet 10b of a keyboard 10 is folded back at the end surface to bring it into face contact with a back plate 11 so as to be grounded so that static electricity charging an operator's body is not transmitted to an LSI 12b on a print base plate 12 via an FPC connector 12a from an FPC 10 of the keyboard 10 before the operator manipulates the heat-cooking apparatus. The side of the back plate 11 of the keyboard 10 is coated with an adhesive 10b. Therefore, the aluminum sheet 10b can be fixed to the side of the back plate 11 of the keyboard 10 by folding back the key board 10 at its end surface, and further by bringing the key board 10 into thick contact with the back plate 11, the aluminum sheet 10b can be brought into face contact with the back sheet 11 thereby to be grounded.
