PROBLEM TO BE SOLVED: To provide a stator structure of rotary electric machine wherein variation in the laminate dimensions of split cores can be eliminated and the enhancement of assemblability and cost reduction can be accomplished. SOLUTION: The stator structure is for rotary electric machines with multiple-shaft and multilayer construction in which an outer rotor 103 and an inner rotor 102 are disposed outside and inside a cylindrical stator 101. The stator construction is formed by disposing a plurality of split cores 201 constituting the stator in the circumferential direction between fixing members provided at both the ends of the stator. A wedged member 207 is disposed between each split core and one of the fixing members. The wedged members are pressed from outer radius toward inner radius to apply pressing force to the split cores in the axial direction, and the split cores are thereby fixed between the fixing members.
