PROBLEM TO BE SOLVED: To uniformly cook rice by the thermal conductivity of a pot without the lack of heating in a pot side surface part even in a simple shape by one block of induction coils. SOLUTION: A cooker 10 is formed in such a way that the inner side of a side surface lower part 10b is largely inclined by 10 deg.-45 deg. and also a bottom surface part 10a is connected to the side surface lower part 10b in a round shape. Then the induction coil is not required to be divided and arranged in the outer side surface lower part and the bottom part lower surface of an inner frame. Only one block of continuous induction coils 4 and 5 are arranged on the outer surface of the inner frame 2 so that rice is uniformly cooked by the thermal conductivity without the lack of heating in the circumference of the side surface part of the cooker 10.
