Abstract
A stator includes a stator core, stator windings provided in the stator core, and a busbar connected to coil end portions of the stator windings. The busbar is composed of a flat conductor body and has a main body portion extended in a circumferential direction in parallel to a circumference of the stator core and multiple protruding portions extended radially from the main body portion. The protruding portions and the coil end portions are joined by laser welding. A thickness of each of the protruding portions in a laser beam emitting direction in which a welded portion is irradiated with a laser beam during the laser welding is greater than a plate thickness of the main body portion in the same direction.
