PURPOSE: Structure for installing a main substrate of a microwave oven is provided to simply connect a substrate holder and to realize firm connection with a small number of components by properly using fixing structure and connecting screws. CONSTITUTION: Fixing slots(48,48') are formed on a substrate holder(40). Fixing pieces(28,28') are formed on a back plate(26) of a cavity(20). The fixing slots are temporarily fixed with the fixing pieces. The substrate holder is connected with an insulator(37) installed on the cavity by using connecting screws(s). A connecting leg(49) of the substrate holder is connected by using the insulator and the connecting screws. Therefore, the substrate holder is connected simply.
