To provide a method and a device for manufacturing a stacked iron core which has a uniform and wide smoothing face at the inner circumferential end of a stator.

Since perfectly circular scrap half blanking 31 is performed in a scrap half blanking process, a wide section does not exist in a scrap 45, so a break with a large area due to the action of a tensile force is not caused at the inner circumference Cis of the stator. That is, only a very small broken-out section 46 on a level that does not cause deterioration of performance of a product occurs at the lower part of the inner circumference Cis of the stator. That is, in the inner circumference Cis of the stator, only the very small broken-out section 46 on a level that does not cause deterioration of performance of the product occurs at the lower part, and the area of the smoothing face 47 is widened.
