A microwave oven has a control unit with a memory to control heat cooking process according to a cooking program for a menu name selected. The control unit includes a liquid crystal display on which character data or image data are displayed as cooking information in plural display areas and a transparent electrode switch sheet in which are arranged plural transparent electrode switches. Keys of the control unit are formed by overlaying the transparent electrode switch sheet to the liquid crystal display such that each electrode switch of the overlaid transparent electrode switch sheet corresponds to the position of one of the plural display areas of the liquid crystal display. In the display area of each key is displayed the character information or image information stored as cooking information in the memory. When a user refers to the character information or image information shown in the display area of the key and operates the key required to select a desired menu name, the transparent electrode switch corresponding to the operated key operates, thereby executing a procedure corresponding to the character information or image information displayed in that display area, and the menu name desired by the user is selected.
