<P>PROBLEM TO BE SOLVED: To improve output properties by reducing leaked magnetic flux, while firmly keeping a plurality of split cores. Ž<P>SOLUTION: A stator 1 for rotating electrical machines has a plurality of split cores 2, on which stator winding 10 is wound toroidally and which are segmentalized in its circumferential direction so that are annular, and a holding member 3, which joins with the periphery of the split cores 2 and keeps the plurality of split cores 2 annular. Each split core 2 has a yoke 22, which has a winding section 21 on which the stator winding 10 is to be wound and is extended in its circumferential direction from the winding section 21; a junction 23, which is extended outward; in its radial direction from the yoke 22 and has a junction face 23a to be joined with the holding member 3; and a tooth 24, which is extended inward in its radial direction from the yoke 22. The junction 23 is equipped with a cut 25, which is a magnetic gap forming means, or weld marks 25a' and 25b' so that the magnetic resistance in a passage for magnetic flux leaked to the holding member 3 via the junction 23a is enhanced.
