Abstract
A microwave heating apparatus includes, within a heating room, a placement table having a horizontal placement surface for placing an object to be heated, and a plurality of feeding portions which are placed on a wall surface of the heating room for supplying microwave electric power to the heating room. The microwave heating apparatus is adapted to relatively move the position of the straight line connecting two feeding portions to each other, with respect to the object to be heated, through a movement mechanism portion, and to detect a phase difference between the microwave electric powers which minimizes reflected electric power returning from the heating room to the two feeding portions, for detecting the state of placement of the object to be heated on the placement table.
