By arranging the heating film 20 on the inner wall of the heating cavity 2, the heating film 20 is used to heat and radiate heat to bake food. Since the heating film 20 is a sheet-shaped heating body, it heats in the form of a whole sheet, so the distance of the surface of the whole food from the heating body is equal. Therefore, when the food is heated and baked by the heating film 20, the surface of the food is uniformly heated, so the cooking progress of each part of the food is the same, so that the situation that part of the food is cooked and part is not cooked at the same baking time does not occur. Since each part of the surface of the food is heated to the same degree, the baking time of the food can be further controlled, so that the baking quality of the food can be effectively guaranteed.
