Claim 13:
14. A stator comprising:
a stator core that includes a core back portion having an annular shape and with a central axis as a center, and tooth portions extending from the core back portion to an inside in a radial direction and arranged in a circumferential direction;
insulators that are attached to the tooth portions from the inside in the radial direction;
a coil that is wound around the insulator; and
a cover that supports an inner surface of the insulator opposing the inside in the radial direction from the inside in the radial direction; wherein
the coils are connected to each other by a jump wire extending along the circumferential direction on one side of the coil in an axial direction;
a plurality of the jump wires are bound by a binding band,
the cover includes a cover body portion positioned on one side of the coil in the axial direction and on another side of the jump wire in the axial direction;
