Original Abstract Submitted
A method for manufacturing a rotor core includes forming core piece blocks and forming a block body that forms a first end face in a stacking direction of the rotor core. The forming each core piece block includes adjusting, when forming a first passage block adjacent to a second passage block, a number of stacked iron core pieces forming the first passage block such that a lamination thickness of the iron core pieces stacked from a first end face to a contact surface of the first passage block with the second passage block falls within a target range, and setting, when forming the second passage block, a number of the stacked iron core pieces forming the second passage block to a predetermined constant number.
