Abstract
Stacked core sheets forming a stacked core of a rotating electric machine have tooth portions on the inner circumferential side. Axial-direction holes penetrating the stacked core in the axial direction are provided near the tooth bases and near the outer circumferential surface. Resin is injected through tooth base neighbor holes near the tooth bases and core outer circumferential holes near the outer circumferential surface of the stacked core, among the axial-direction holes in the rotating electric machine. Thus, the resin fills gaps near the tooth bases and near the outer circumferential surface of the stacked core, so that the stacked core sheets are bonded to each other, thus obtaining a rotating electric machine having such a stacked core.
