The hole 18 is provided so that supersonic waves may be transmitted into the heating chamber 3 by way of a reflection plate 19. Radio waves are irradiated to foodstuffs which are being rotated by a rotary dish 4. More specifically, the pulse- shaped radio waves are irradiated at a short interval intermittently. At the same time, it is contrived that reflection waves from the foodstuffs or occasionally from the wall surface of the heating chamber 3 are received. At that time, the supersonic waves transmitted by a supersonic vibrator 17 to which a horn 20 is attached, are turned into highly efficient supersonic pulses where the horn 20 converts mechanical energy into acoustic energy efficiently. Resulting from this, the sensitivity of received waves are upgraded. The differential time serves to detect the presence of foodstuffs or measure the distance between the vibrator and the foodstuffs, while the data described above can help to recognize the outlined shape of foodstuffs.
