PROBLEM TO BE SOLVED: To properly retain magnetic characteristics of a stator by suppressing the effect of non-uniform magnetic flux generated at a locking part of a divided core in the stator for a rotary electric machine equipped with a toroidal winding structure constituted by annularly connecting a plurality of split cores. SOLUTION: In the stator 1 composed by the plurality of divided cores 2 split in a circumferential direction in units of winding parts around which a stator winding 4 is wound, each split core 2 has the locking part composed of a recessed part 14 and a protruding part 15 which are fitted to each other in order to regulate the relative movement between adjacent split cores, and in the winding part when an electric current is made to flow into the stator winding 4, the locking part is provided at a site where the magnetic flux density becomes minimum in the radial direction.
