To provide a microwave heating apparatus capable of heating various objects to be heated having different configurations, kinds, sizes, and amounts contained in a heating chamber with high efficiency by keeping low a reflected power of a microwave radiated from microwave supplying means, a microwave generator part includes oscillator parts (2a, 2b), power divider parts (3a, 3b), power amplifier parts (5a-5d), a heating chamber (10) containing the object to be heated, and a plurality of feeding parts (8a-8d, 9a-9d) arranged in a wall surface of the heating chamber to supply the microwaves therein, in which a phase difference and oscillation frequencies outputted from the feeding parts controlled as a pair are variably controlled. |
