A rotating electrical machine includes: a stator core having a plurality of slots formed therein; a stator winding assuming a plurality of phases, which includes a plurality of round windings wound with a wave winding pattern, each having slot conductors each inserted at one of the slots at the stator core to form one of a plurality of layers and cross conductors each connecting same-side ends of slot conductors inserted at different slots so as to form a coil end; and a rotor rotatably supported with an air gap so as to be allowed to rotate relative to the stator core, wherein: the cross conductors connect the slot conductors so as to run astride slots with the slot pitch Np set to N + 1 at coil ends on one side and run astride slots with the slot pitch Np set to N - 1 at coil ends on another side, with N representing a number of slots per pole; the stator winding includes a plurality of slot conductor groups each having a plurality of slot conductors corresponding to a single phase; the plurality of slot conductors in each slot conductor group are inserted at a predetermined number Ns of successive slots forming a continuous range along a circumference of the stator core so that the slot conductors in the slot conductor group take successive slot positions and successive layer positions; and the predetermined number Ns is set so that Ns = NSPP + NL when NSPP represents a number of slots per phase per pole and a number of layers is expressed as 2 x NL.
