Stator core for rotating electric machine

A stator core for a rotating electric machine includes a plurality of split cores. Each of the plurality of split cores includes a back yoke, a tooth, and a single caulking portion. When each of the plurality of split cores is seen in an axial direction, two inner circumferential-side intersections and two outer circumferential-side intersections are defined, both circumferential-end surfaces of the tooth intersect an inner circumferential surface of the back yoke at the two inner circumferential-side intersections, virtual lines drawn by extending both the circumferential-end surfaces of the tooth intersect an outer circumferential surface of the back yoke at the two outer circumferential-side intersections, a central position of the caulking portion is disposed in an opposing angular region on a radially outer side out of four opposing angular regions defined by lines diagonally connecting the two inner circumferential-side intersections to the respective two outer circumferential-side intersections.
