| description | Provided are a laminated core manufacturing method for a rotating electrical machine, a laminated core manufacturing device, and a rotating electrical machine, capable of improving motor efficiency and suppressing cogging torque or torque pulses. The method comprises steps that before a step of punching a plate-shaped rotor core element (21) from a rolled strip-shaped electromagnetic steel plate (4) by a punching mechanism (51,...), the plate-shaped rotor core element (21) is punched in a second region (42) of the strip-shaped electromagnetic steel plate (4) that is further inward than a firstregion (41) of the punched plate-shaped rotor core element. The plurality of plate-shaped stator core elements (11) are punched by a punching step so that the tooth portions (11T) extend in the samedirection in the radial direction of the rotating electrical machine.
