Summary:PROBLEM TO BE SOLVED: To solve such a problem that, since a punched plate on a bottom face of a cooking chamber, which blocks a microwave and passes magnetic flux, has a short life, due to high frequency of use in a professional use, in conventional structures, it takes time to replace and repair the punched plate, so that operating efficiency is lowered. SOLUTION: A round opening is provided on a base plate 71 forming a bottom of the cooking chamber, and an annular base plate fitting 73 welded with the punched plate 72 is removably attached to the round opening. The base plate fitting 73 is fixed to the base plate 71 by the combination of: a fixing part 75, which is screwed by a weld bolt fixed to the base plate 71 with a nut; and a pressure welding part 78 simply pressed by a convex part 73b, so that necessary strength is secured, while improving the operating efficiency.
