摘要：
A plurality of strips formed with tooth portions and core back portions is punched from a single band of sheet steel. Next, a plurality of strips is stacked such that the tooth portions line up together and the core back portions line up together and the stacked plurality of strips is integrated to form a strip lamination. Then, the strip lamination is wound spirally and the wound strip lamination is integrated to obtain a stator core.
