PROBLEM TO BE SOLVED: To provide a cooking device for induction-heating/defrosting food material with high frequency while cooling the surface of the food material, lowering the manufacturing cost, stabilizing cooling performance in a cooking chamber, and performing high-quality defrosting at a low cost. SOLUTION: The cooking chamber 25 is provided in a space of a cooling chamber 22 opened to a front face, the space is used as a cold air circulating passage, the weight of food material in the cooking chamber 25 is detected by a motor 45 for food tray rotation and according to a food material weight detection signal, high frequency output from a high frequency generation means (high frequency generator 64) is controlled and high frequency wave is diffused, whereby the number of parts of the cold air circulating passage is decreased to simplify the shape of a thermal insulating box body, decrease quantity of air in the cold air circulating passage and the cold air inlet 43 part is restrained to efficiently supply cold air to the surface of the food material. Thus, the surface temperature of the food material is kept constant and weight-oriented heating control of the food material is conducted and the food material can be evenly heated, the cooking device is manufactured at a low cost and can perform high-quality defrosting.
