Beschreibung
Zusammenfassung:	A microwave oven has a heating chamber (10) formed inside a body frame (5). A radiation antenna (15) is provided below the heating chamber (10). The radiation antenna (15) is structured in such a way that a member housed in an antenna drive box (16) appropriately operates to change the distance between a bottom surface (5X) of the body frame (5) and the radiation antenna (15). Microwaves generated by a magnetron (12) are supplied through a waveguide (19) and the radiation antenna (15) into the heating chamber (10). When the level at which the radiation antenna (15) is positioned is changed, the way to supply microwaves from the radiation antenna (15) into the heating chamber (10) is accordingly changed. Specifically, microwaves are locally supplied into the heating chamber (10) or supplied uniformly into the whole of the heating chamber (10).
