Claim 7:
8. The microwave heating device of claim 7, wherein the radiation elements include two or more radiation elements aligned in a first alignment direction and two or more radiation elements aligned in a second alignment direction;
wherein the phase shifter makes a difference in phase between the radiation elements each provided in a corresponding one of the first alignment direction and the second alignment direction;
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 the first alignment direction, and two or more hollow dielectric members provided in a line along one of the walls which crosses a straight line extending in the second alignment direction; and
wherein the processing circuitry controls: at least one of the hollow dielectric members provided along the wall which crosses the straight line extending in the first alignment direction; and at least one of the hollow dielectric members provided along the wall which crosses the straight line extending in the second alignment direction; to be put into the plasma state in which the microwave is absorbed.
