To improve the power efficiency without significantly increasing the cost by forming a salient on the outer surface of a cooking vessel.

The induction heating type cooker that is equipped with the cooking vessel (inner pan 3) that is heated by induction heating with an IH coil 10 can improve the power efficiency by integrally forming a salient part 33 opposite to the IH coil 10 on the outer surface of the cooking vessel (inner pan 3) to increase the surface area of the part of the cooking vessel (inner pan 3) that faces the IH coil 10 and to reduce the distance from the IH coil 10 for being exposed to stronger magnetic flux.
