[Problem] To decrease constraints on a heating method that result from electromagnetic wave interference in an electromagnetic wave heating device using an electromagnetic wave generation device comprising a semiconductor element. [Solution] An electromagnetic wave heating device is provided with: a heating chamber; a first planar antenna that is disposed on a first wall surface of the heating chamber and emits an electromagnetic wave for heating a target object inside the heating chamber; a second planar antenna that is disposed on a second wall surface, which is different than the first wall surface, of the heating chamber and emits an electromagnetic wave for heating the target object inside the heating chamber; an oscillator that comprises a semiconductor element and outputs an electromagnetic wave; a switching unit that feeds the output of the oscillator to either the first or second planar antenna; and a control unit that controls the switching unit and an electromagnetic wave generation device. |
