Abstract
A method for manufacturing a laminated iron core includes preheating a laminated body in which a plurality of iron core pieces are laminated and which includes a resin filling hole, measuring a temperature of the laminated body after preheating the laminated body, determining whether or not the temperature measured is within a predetermined range, feeding the laminated body into a molding device in a case where it is determined that the temperature is within the predetermined range, and filling the resin filling hole of the laminated body with a resin material in the molding device.
