A manufacturing method for a rotary electric machine core includes a lamination step in which a plurality of steel plates is laminated so that a laminated body is configured, a heating step in which the laminated body is heated to a specified target temperature, a pressurization step in which the laminated body is pressed by a pressurization member until a pressure load reaches a target load larger than a specified fastening load in a state where the laminated body is heated to the target temperature, the pressurization member is then made to stand still until the pressure load is constant, and, once the pressure load is constant, the pressurization member is moved away, and a fastening step in which, after the heating and the pressurization are stopped, the steel plates that configure the laminated body are fastened by a fastening part until the fastening load is generated.
