ABSTRACT:
A microwave oven whose door screen is constructed by interposing an electromagnetic wave shielding body of a metallic plate having a plurality of through-holes formed therein or a wire screen, between a tempered glass plate and a transparent resin plate, with the tempered glass plate being placed on the side of a heating cavity while the transparent resin plate being placed outwardly, a peripheral section of the shielding body extending to electrically connect with a metal plate which, essentially, electrically connects the heating cavity with the door body, whereby observation of food in the heating cavity during cooking can be facilitated while the safety from electromagnetic wave leakage is assured.
