Abstract: A method for manufacturing a laminated core, in which while a laminated core body 10 formed by caulking and with permanent magnets 20 inserted in a plurality of magnet insertion holes 17, 18 is held between a resin injection die 23 and a receiving die 22 opposed to each other, resin is injected into the magnet insertion holes 17, 18 from resin reservoir portions provided to the resin injection die 23 to fix the permanent magnets 20, the method comprising: at a time of resin injection, pressing a flat press surface 24 of the resin injection die 23 against caulking portions 13 protruding from a surface of the laminated core body 10 to apply pressure thereto, thereby allowing the surface of the laminated core body 10 whereon the caulking portions 13 are formed to be pressed against the flat press surface 24 so as to prevent resin leakage.
