Abstract
A manufacturing method for a laminated core of a rotating electric machine includes a laminating step and a core separating step. In the laminating step, a plurality of core elements are laminated, thereby forming an element laminate. In the core separating step, under a state in which the element laminate is pressed in a lamination direction of the plurality of core elements, a part of the element laminate is moved from the element laminate in a direction orthogonal to the lamination direction by a set dimension in the lamination direction, thereby obtaining a separated laminate.
