PROBLEM TO BE SOLVED: To suppress variation in relative position of core segments in the axial direction of a rotating electric machine, and to equalize the clamping force of each core segment. SOLUTION: A stator core 12 has a plurality of core segments 18 split in the circumferential direction of a rotating electric machine, and a substantially cylindrical clamping member 20 for clamping the plurality of core segments 18 by tightening them from the outer circumferential side. A plurality of protrusions 32 protruding radially inward of the rotating electric machine are arranged on the clamping member 20 along the circumferential direction of the rotating electric machine with a gap therebetween. Each of the plurality of protrusions 32 has a surface 32a abutting against one end face 18a of each core segment 18 in the axial direction of the rotating electric machine, and thereby each core segment 18 is positioned in the axial direction.
