A stator includes an annular stator core and a multi-phase stator coil. The stator core has slots arranged in a circumferential direction thereof. The stator coil is comprised of phase windings that are mounted on the stator core so as to be received in the slots of the stator core. The stator coil has an annular coil end part protruding axially outward from an axial end face of the stator core. The stator coil includes, at least, two lead wires and a joint. Each of the lead wires is connected with one of the phase windings of the stator coil and led out from a radially inner periphery of the coil end part. At the joint, distal ends of the lead wires are joined to each other. Adjoining portions of the lead wires, which adjoin each other, are arranged radially inside a radially-inner peripheral surface of the coil end part.
