Abstract
A laminated iron core is made of a stator iron core formed by laminating a plurality of iron core pieces with a predetermined shape, and a caulking block detachable along a radial direction is formed in each of the iron core pieces. In a method for manufacturing the laminated iron core, the caulking block detachable along the radial direction is provided in each of the iron core pieces, and the iron core pieces are laminated and joined through the caulking blocks and are arranged on a jig and then, the caulking blocks are pulled in the radial direction and are detached from the laminated iron core pieces, and the laminated iron core pieces are joined by a resin.
