description PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminated core that is made by connecting divided laminated cores each having a divided yoke and teeth, which enhances productivity of the laminated core and achieves production cost reduction. SOLUTION: The method of manufacturing the laminated core includes steps of: punch-forming a rotator iron core sheet piece 20 from a sheet material W; shearing and bending the connections 11A, 11B of adjoining divided iron core sheet pieces 11 a yoke forming region where divided iron core sheet pieces 11 are mutually connected; punching out the contours of the divided iron core sheet pieces 11 to dividedly form the individual divided iron core sheet pieces 11; and laminating the divided iron core sheet pieces 11 on the under-layer divided iron core sheet pieces 11 punch-formed in advance, and caulking them.
