PROBLEM TO BE SOLVED: To obtain a stator of a rotating electric machine which can suppress an increase in current loss caused by a flow of a circulating current in an element wire conductor as a whole in an armature winding. SOLUTION: A stator core 3 has a plurality of winding slots 6 which extend in the axial direction at the internal peripheral face of the core and are arranged in parallel with one another, average magnetic-body space factors at both ends of the axial direction and in the center of both the ends are made equal, the armature winding 2 is accommodated in the winding slots 6, a half-turn coil of an upper coil 2c and a half-turn coil of a lower coil 2d are constituted by binding the multiple element wire conductors, the element wire conductors are short-circuited at the half-turn coil of the upper coil 2c and the half-turn coil of the lower coil 2d, respectively, at coil ends which further extend via linear parts 2e outwardly protruding from both side ends of the stator core 3, respectively, the element wire conductors of the linear parts 2e extending to the outside from both side faces of the stator core 3 in the winding slots 6 of the stator core 3 are formed so as to be dislocated by continuously being twisted, and dislocation angles of the half-turn coils as a whole are set larger than 360°.
