An object of the present invention is to provide a high-frequency heating apparatus capable of obtaining a desired cooking finish suitable for the type of a subject to be heated and also improving a heating efficiency even when a grill menu is chosen. A high-frequency heating apparatus of the present invention includes a heating chamber to which a heating plate for loading a subject to be heated thereon is detachably attached, a microwave generating unit, a waveguide for transmitting a microwave from the microwave generating unit, a rotation antenna for radiating the microwave into the heating chamber from the waveguide, a driving unit for turning/driving the rotation antenna, an operating portion capable of choosing the grill menu by which the subject to be heated put on the heating plate is heated and a hot-up menu by which a heated plate is heated without the heating plate, and a controlling unit for controlling the driving unit based on an output signal from the operating portion, wherein the controlling unit controls to vary a direction of a sharp portion of a radiation directivity of the rotation antenna in response to the output signal from the operating portion. |
