ABSTRACT:
A rotating electric machine armature core is configured by combining such a number of magnetic tooth sections that corresponds to the number of magnetic poles, each of the magnetic tooth sections including a plurality of first sheet members each of which includes a magnetic tooth portion formed at one end and a root portion formed at the other end with an end face of the root portion having a prescribed external shape, and at least one second sheet member inserted between the individual first sheet members in a laminating direction thereof at a location different from the locations of the other sheet members, the second sheet member including the magnetic tooth portion formed at one end and an overlapping portion formed at the other end, the overlapping portion forming a back yoke portion together with the root portion with a through hole formed at a specified position in the overlapping portion, the overlapping portion jutting out from the root portion in such a manner that the overlapping portion can fit on the end face of the root portion of the first sheet member, wherein the magnetic tooth sections are combined in a radial form with the through holes in the individual overlapping portions aligned at the same location.
