The invention provides a stator coil of a rotating electrical machine. The stator coil includes: a plurality of phases of stator phase coils, each stator phase coil including multiple round coils formed by round-wound slot conductors inserted into the slots of a stator core and forming any one of multiple layers and cross conductors for connecting the same side end portions of the slot conductors inserted into different slots to form a coil end. In the stator coil of the rotating electrical machine, the round coil is formed by multiple segmented coils connected at one coil end. When the number of slots of each electrode is N, the cross conductcrosses the slots at a slot pitch Np=N-1 at the coil end connected with the segmented coil and connects the slot conductors at a slot pitch Np=N+1 at the other coil end. The stator phase coil is formed by stator coil groups in the same phase and without phase difference.
