Abstract
According to one embodiment, a stator includes a stator core and a stator coil configured by joining a plurality of coil segments mounted in slots of the stator core. Extending portions of the coil segments include a plurality of first extending portions, an inclined portion, and a joining end portion and a hook-shaped portion provided at an extending end of the inclined portion. The joining end portions are arranged side by side in a radial direction such that distal end surfaces are located at substantially the same height, the hook-shaped portions are meshed with each other, and a first engagement surface of one of the joining end portions faces and abuts on a first engagement surface of the other of the joining end portions.
