the control
20 unit may be configured to (i) estimate by calculation an amplitude and a phase of the reflected wave and an amplitude and a phase of the through wave resulting from a given combination of the phase shift amounts in the variable phase shift unit, with respect to each of the frequencies that can be set for the radio-frequency power generation unit, by using the detected amplitude and phase of the reflected wave and the detected amplitude and phase of the through wave, and (ii) determine a frequency of the radio-frequency power to be generated by the radio-frequency power generation unit and a combination of the phase shift amounts of the variable phase shift unit to be applied for heating the object, on the basis of (a) the amplitude and the phase of the reflected wave and the amplitude and the phase of the through wave detected with respect to each of the frequencies, and (b) the amplitude and the phase of the reflected wave and the amplitude and the phase of the through wave resulting from given combinations of the phase shift amounts in the variable phase shift unit, estimated with respect to each of the frequencies.

the control unit may be configured to determine, among the given combinations, the combination in which a total amount of the reflected wave and the through wave detected by the backward power detection unit of each of the radio-frequency power units is smallest.

Such a configuration allows each of the radio-frequency power units to radiate the radio-frequency power to the heating chamber independently from one another, thereby facilitating the detection of the reflected wave and the through wave.
