PROBLEM TO BE SOLVED: To provide a rotating electrical machine which can stably support the coil end of a stator even if the number of installed spacers is reduced. SOLUTION: Stator coil ends 3E jutted from stator cores 2 are bound together and supported with a plurality of supporting rings 5A-5C, and also spacers 8 are installed in the vicinity of adjacent stator coil ends of different phases (U, V, and W) between the supporting rings 5A-5C, thus the stator coil ends 3E that the spacers 8 contact are bound and supported with one another. By installing the spacers 8 only in the vicinity of the stator coil ends 3E of different phases adjoining each other in its circumferential direction where a large electromagnetic force works between the supporting rings 5A-5C, the number of installed spacers 8 can be reduced, and the stator coil ends 3E of different phases can be supported firmly, so that the stator coil ends can be supported stably.
