A rotating electric machine armature core ( 1 ) is configured by combining such a number of magnetic tooth sections ( 2 ) that corresponds to the number of magnetic poles, each of the magnetic tooth sections ( 2 ) including a plurality of first sheet members ( 6 ) each of which includes a magnetic tooth portion ( 3 ) formed at one end and a root portion ( 5 ) formed at the other end with an end face of the root portion ( 5 ) having a prescribed external shape, and at least one second sheet member ( 10 ) inserted between the individual first sheet members ( 6 ) in a laminating direction thereof at a location different from the locations of the other sheet members, the second sheet member ( 10 ) including the magnetic tooth portion ( 3 ) formed at one end and an overlapping portion ( 9 ) formed at the other end, the overlapping portion ( 9 ) forming a back yoke portion ( 8 ) together with the root portion ( 5 ) with a through hole ( 7 ) formed at a specified position in the overlapping portion ( 9 ), the overlapping portion ( 9 ) jutting out from the root portion ( 5 ) in such a manner that the overlapping portion ( 9 ) can fit on the end face of the root portion ( 5 ) of the first sheet member ( 6 ), wherein the magnetic tooth sections ( 2 ) are combined in a radial form with the through holes ( 7 ) in the individual overlapping portions ( 9 ) aligned at the same location.
