PROBLEM TO BE SOLVED: To provide a microwave heating device capable of uniformly heating a heated object.SOLUTION: The microwave heating device comprises: a heating chamber 1 in which a heated object 7 is put; a location part 2 for locating the object; microwave supply means 3 for supplying microwaves; a waveguide 4 for transmitting the microwaves to the heating chamber 1; and a microwave radiation part 5 for radiating the microwaves to the heating chamber 1. A reflector plate 6 arranged from a first position that is within 1/4 of wavelength of the microwave from a center of the microwave radiation part 5 on the same plane as the microwave radiation part 5 toward a second position that is located at an end of or inside the end of the location part 2 on the same plane as the location part 2 is provided between the microwave radiation part 5 and the location part 2. The microwave can be widely radiated to the heating chamber 1 without using rotation mechanism such as a turntable and a rotation antenna, and therefore, the heated object 7 on the location part 2 can be uniformly heated. |
