Manufacturing method for laminated iron core and laminated iron core

A manufacturing method for a laminated iron core, the manufacturing method comprising:

• a punching process of punching a metal sheet to form a plurality of punched members including a first punched member having a first shape and a second punched member having a second shape different from the first shape;
• and
• a laminating process of forming a laminated body by laminating the plurality of punched members while changing a rotational lamination angle each time one or more punched members are laminated, the rotational lamination angle representing an angle of the punched member in a circumferential direction,
• wherein in the laminating process, the plurality of punched members are laminated such that the rotational lamination angle is the same between the first punched member and the second punched member adjacent to each other in a boundary portion between two or more of the first punched members that are continuously laminated and two or more of the second punched members that are continuously laminated.
