Summary:A microwave heating device according to the present invention includes a microwave oscillation portion (10a) including a reference-signal oscillator (11) formed from a quarts oscillator, phase variable portions (12a to 12b) and phase-locked loops (13a to 13d) and, further, includes a control portion (22) for controlling the microwave oscillation portion (10a), and plural radiation portions (20 and 21) placed on a wall surface of a heating chamber (100) for housing a to-be-heated object, wherein microwaves supplied to plural microwave feeding points (20a, 20b and 21a, 21b) provided in the radiation portions (20, 21) are controlled in phase and electric power, thereby controlling the aspect of radiations of microwaves radiated from the radiation portions (20, 21).
