PROBLEM TO BE SOLVED: To provide a cooker inner pan provided with a heating layer formed of electroplated coatings or the like produced by substantially not using a plating mask or the like, strongly heating a specified region in a range of thicknesses enough to obtain calorific power and strength, hardly heating other regions and able to enlarge a temperature distribution. SOLUTION: In the heating layer 7 formed on the outside 11 of an inner pan body 1 and simultaneously functioning as a heat conduction layer, an eddy current loss in the region facing an induction coil of an electromagnetic cooker is made larger than that in the other region, which results in that each of alloy composition ratios in both regions is set in a different extent.
