PURPOSE: The resonance mode transform unit is activated. In that way only the scan duration does not repeat continuously. The heating zone can operate, a heating efficiently can operate. CONSTITUTION: A cooker using a microwave comprises a microwave generating unit, a oscillating mode changing unit, and a controller. It is created a plurality of microwaves for heating the object of the cavity inside and the microwave generating unit outputs(S410). The resonance mode transform unit at least varies one within cavity among the progressive direction of the outputted microwave, and the power and the frequency, the resonance mode is changed(S430). According to the microwave which the controller is reflected to among the outputted microwave from the cavity inside, the number of frequency of microwave more than the standards efficiency is less than the standard value based on the heating efficiency, it controls so that the resonance mode transform unit act(S435).
