A stator core for a rotating electrical machine includes an annular yoke portion; a tooth group fitted to an inner side of the yoke portion and formed such that both ends in a circumferential direction on an inner circumferential side of adjacent teeth are integrally connected with each other by a thin connection portion; and a slot for accommodating a stator winding. The yoke portion has grooves at regular intervals in an inner circumferential surface thereof and extending in an axial direction of the stator, the grooves each having a V shape such that a cross section thereof perpendicular to the axial direction opens toward an inner side of the stator core. Each tooth has, at an outer-circumferential-side end thereof, a fitting portion whose cross section perpendicular to the axial direction is formed in a wedge shape so as to allow the tooth to be fitted along the corresponding groove.
