A microwave oven comprises a microwave generator, a heating chamber, a waveguide for leading microwaves from the microwave generator to the heating chamber, a blower for generating air current in the waveguide, a microwave stirring member rotated by air current from the blower member for stirring microwave from the microwaves generator. The microwave stirring member comprises a rotating member being substantially vertical to the microwave propagation direction and having the rotation axis in the center, and microwave reflecting members with fins. The rotating member has a microwave receiving member substantially vertical to the microwave propagation direction, in the rotation center thereof, to receive microwave intensively, and a microwave feeding or radiating member extending from the rotation center and electrically communicating with the microwave receiving member, to feed or radiate microwaves in the heating chamber.
