The purpose of the present invention is to provide: a stator for a dynamo-electric machine, with which axial size can be reduced; and, an electrically powered wheel provided with the stator for the dynamo-electric machine. A stator for a dynamo-electric machine is provided with a stator core , a plurality of coils A-D, and jumper wires A-C. The stator core has first teeth around which a coil is wound and second teeth around which a coil is not wound. The first teeth and the second teeth are disposed alternatingly in the circumferential direction. The jumper wire extends circumferentially and radially with a bent section to absorb variations in the spacing between one coil and another, and is disposed at a position overlapping the second teeth when viewed from the axial direction of the dynamo-electric machine. Further, the jumper wire is disposed closer to the stator core relative to an axial end of a coil at least partially wound around the first teeth
