Claim:
1. A microwave heating device comprising: a heating chamber adapted to house an object to be heated; a microwave supply portion for supplying microwaves to the heating chamber; a waveguide tube for propagating microwaves supplied from the microwave supply portion, to the heating chamber; a plurality of microwave radiating portions which are formed on the waveguide tube and are for radiating microwaves propagating through the waveguide tube, to inside of the heating chamber; and a heating-chamber input portion which is adapted to direct, to the inside of the heating chamber, microwaves having propagated through the waveguide tube and having passed through positions where the microwave radiating portions are formed, to realize a state where a progressive wave is dominant, among the microwaves propagating through the waveguide tube; wherein the microwave radiating portions are adapted to radiate, to the inside of the heating chamber, microwaves based on the progressive wave propagating through the waveguide tube.
