Abstract
A method of manufacturing a stacked core includes forming a first pilot hole in a metal plate, forming a worked portion of the metal plate in a state in which a first pilot pin is inserted into the first pilot hole, the worked portion being displaced relative to a plane of the metal plate, press-fitting the worked portion of the metal plate to reposition the worked portion to extend along the plane of the metal plate, forming a second pilot hole in the metal plate after press-fitting the worked portion of the metal plate, and forming a blanked member by blanking the metal plate in a state in which a second pilot pin is inserted into the second pilot hole, the blanked member including the worked portion.
