A coil includes first and second segment conductors, and a welded metal portion where the first and second segment conductors are welded. The first and second segment conductors each include: a fixed portion held in a stator core to extend in a first direction; an inclined portion protruding from the stator core, extending in a second direction inclined with respect to the first direction, and including side surfaces covered with an insulative coating film; and a weld portion that is at a tip of the inclined portion and includes a first surface located within an extension plane in the second direction of one surface of the side surfaces, a second surface contacting the first surface, and a third surface contacting the second surface. The welded metal portion contacts the first, second, and third surfaces of the first segment conductor, and the first and second surfaces of the second segment conductor.
