PROBLEM TO BE SOLVED: To provide an inner pot which eliminates a need for keeping thermal uniformity by heat conduction caused by the thickness of the inner pot by arranging an induction heating coil in a wide range of the inner pot so as to evenly heat the whole of the inner pot and achieves excellent handleability with a light weight by making the inner pot thinner. SOLUTION: A material of the inner pot 2 is composed of a single material of stainless steel, titanium or a titanium alloy and the induction heating coil 4 is divided into a plurality of parts from the bottom surface of the inner pot 2 to an upper part of the side thereof. The range in which a plurality of the parts of the induction heating coil 4 are connected together is so arranged as to cover a wide area of the inner pot 2 which is at least a half of the upper part of the side from the bottom surface thereof.
