Summary:PROBLEM TO BE SOLVED: To provide a manufacturing method of a core which can integrate a plurality of steel plate components utilizing a part of the outer shape of the core, without push back, and maintains the performance of the core and the yield of steel strip, and adhesively fixes a plurality of steel plate components easily.SOLUTION: In a production method of a core, by performing a punching lamination process, an adhesive fix process, and a cut process, a core 6A is manufactured. In the punching lamination process, by utilizing a part of an outer shape X of the core 6A, a caulking portion 53 is formed which is connected to a steel plate component 50, and the plurality of steel plate components 50 are stacked while caulking by the caulking portion 53. In the adhesive fix process, the plurality of stacked steel plate components 50 are adhesively fixed each other. In the cut process, the caulking portion 53 in the adhesively fixed steel plate components 50 each other is cut so as to form the core 6A.
