Method for manufacturing a laminated core and manufacturing jigs

Provided are a method for manufacturing a laminated core wherein the workability of winding and assembly can be enhanced without degrading the magnetic performance of a laminated core, and a tool for manufacturing same. A core sheet (50), which consists of a tooth (11b) and a back yoke (11a) formed by projecting the tooth (11b) from the arcuate central portion to the center side and fitting a fitting protrusion (12a), which is one of the wings of a butterfly-shaped scrap (12), to the opposite side by push-back, is punched out from a steel plate.  A plurality of the core sheets (50) are laminated, the front and back surfaces of adjoining scraps (12) are fixed to each other by caulking a fixing recess (12d) and a fixing protrusion (12e), the laminated layers of the laminated core (11) are fixed to each other, and then the laminated scrap (12) is removed from the laminated back yoke (11a).
