Summary:PROBLEM TO BE SOLVED: To solve a problem that a service life of a punching board shielding microwaves at a bottom surface section of a cooking chamber, while allowing magnetic flux to pass therethrough, is short as use frequency is high in a case of business use, and it takes a long time for its replacement and repair, which degrades operational efficiency of the device. SOLUTION: A circular opening is formed on a bottom plate 71 forming a bottom section of the cooking chamber, and an annular bottom plate fitting 73 to which the punching board 72 is welded, is detachably mounted thereon. By fixing the bottom plate fitting 72 to the bottom plate 71 by combining a fixing section 75 by engagement of a weld bolt fixed to the bottom plate 71 and a nut, and a pressure contact section 78 by simple pressing of a projecting section 73b, the necessary strength can be ensured while improving work efficiency.
