Provided is a stator core (11) composing a stator (10) for a rotating electrical machine and including: an annular yoke portion (11b); a tooth group (11a) fitted to an inner side of the annular yoke portion (11b) and formed such that both ends in a circumferential direction on an inner circumferential side of adjacent teeth (11a2) are integrally connected with each other by a thin connection portion (11a1); and a slot for accommodating a stator winding (12). The annular yoke portion (11b) has grooves (11b1) provided at regular intervals in an inner circumferential surface thereof and extending in an axial direction of the stator (10), the grooves (11b1) 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 (11). Each tooth (11a2) of the tooth group (11a) has, at an outer-circumferential-side end thereof, a fitting portion (11a3) whose cross section perpendicular to the axial direction is formed in a wedge shape so as to allow the tooth (11a2) to be fitted along the corresponding groove.
