A method for manufacturing a laminated core as well as produced by the method of layered core

In a method for manufacturing a laminated core according to the present invention, the production of the laminated core is performed by linearly arranging and punching a plurality of separate core pieces, which are each formed by a back yoke portion and a protrusion projecting from the rear yoke magnetic-pole teeth area, followed by a stacking and punching caulking. The manufacturing method includes the following steps: a first step of punching out a first region that is located on an opposite side of the magnetic-pole teeth area between adjacent ends of the back yoke portions of the core pieces; a second step of punching out a second region, which is located on one side of the magnetic-pole teeth area between the adjacent ends of the back yoke portions of the core pieces; a third step of punching out a region that connects the punched-out in the first step first region and the punched-out in the second step, second region with each other; and a fourth step of forming the magnetic pole teeth portion by punching.
