Claim 6:
7. The microwave heating device of claim 2, comprising two or more radiation elements included in the at least one radiation element;
wherein the microwave generator has a phase shifter to make a difference in phase between microwaves each of which is the microwave radiated by a corresponding one of the two or more radiation elements;
wherein the hollow dielectric members include two or more hollow dielectric members provided in a line along one of the walls which crosses a straight line extending in an alignment direction of the two or more radiation elements; and
wherein the processing circuitry controls at least one of the hollow dielectric members provided in a line, to be put into the plasma state in which the microwave is absorbed.
