Abstract
A radio-frequency heating apparatus includes a phase varying unit to vary the phase of radio-frequency power; and a plurality of antennas which are placed on the same plane in a heating chamber and radiate a plurality of radio-frequency waves. The radio-frequency waves have a predetermined phase difference caused by phase variation in the phase varying unit. A geometry information acquisition unit acquires the geometry of an object; and a control unit controls the phase varying unit so that the radio-frequency waves are in phase in a first mode, and the radio-frequency waves are in opposite phase in a second mode. The control unit switches between the first mode and the second mode based on the acquired geometry information.
