PROBLEM TO BE SOLVED: To prevent microwaves from directly returning to a microwave introduction port even when the load of a heating object is small and many of the microwaves having introduced from the microwave introduction port are reflected, in a microwave heating device equipped with a microwave introduction port opened on a wall for introducing microwaves in a predetermined orientation direction. SOLUTION: A part in an oven for receiving radiation of the microwaves in an opposite wall facing to the wall with the microwave introduction port formed thereon is tilted by an angle of 5°-40°with respect to a direction perpendicular to the orientation direction of the microwaves.
