Abstract
Provided are: a rotating-electrical-machine stator in which the height of coil ends of a stator coil is suppressed, while interference between adjacent conductors at the coil ends is avoided; and a rotating electrical machine provided with same. The rotating-electrical-machine stator is provided with: a stator core provided with a plurality of slots; and a stator coil inserted into the slots. The rotating-electrical-machine stator is characterized in that: the stator coil is provided with at least two conductors which are disposed in the same layer as a first conductor, and which are inserted into the slots adjacent to the first conductor; and the shapes of coil protrusions protruding radially outwards are configured so as to form arcs.
