A microwave oven including a turntable lifting/lowering device capable of vertically moving a turntable by an operation of a spiral gear, thereby achieving a stability even when a liquid food is cooked, and capable of eliminating use of any supporting member and rotation die adapted to achieve the vertical movement of the turntable, thereby very simplifying the inner construction of a heating chamber. The microwave oven also includes an automatic thawing device capable of eliminating use of any weight sensor and thawing a food on the basis of the total thawing time and the thawing mode determined by use of the temperature of the food and the moisture amount generated from the food varying depending on the processing of the cooking and capable of carrying out the thawing while vertically moving a turntable by a turntable lifting/lowering device, thereby achieving a uniform and sufficient thawing of the food. The microwave oven achieves a grille cooking under a condition that a food to be cooked approximates to a heater by the turntable lifting/lowering device and achieving a combination cooking by heating the food alternatingly by microwaves and the heater while moving a turntable upwards and downwards, thereby uniformly cooking all portions of the food.
