Claim 2:
3. The microwave heating device of claim 2, wherein the at least one hollow dielectric member includes: two or more hollow dielectric members provided in a line at respective positions about 0.25 wavelength away from a first wall among the walls which is other than the wall at which the radiation element is provided; and two or more hollow dielectric members provided in a line at respective positions about 0.25 wavelength away from a second wall among the walls which is other than the wall at which the radiation element is provided, the second wall being opposite to the first wall across the heating target; and
wherein the processing circuitry performs control to make switching between: a first set of states in which the hollow dielectric members provided in a line along the first wall are put into the plasma state in which the microwave is reflected while the hollow dielectric members provided in a line along the second wall are put into the gas state in which the microwave is allowed to be transmitted; and a second set of states in which the hollow dielectric members provided in a line along the second wall are put into the plasma state in which the microwave is reflected while the hollow dielectric members provided in a line along the first wall are put into the gas state in which the microwave is allowed to be transmitted.
