Abstract
A stator includes a stator core, three-phase coils, three external terminals, and three busbars. Each of the three-phase coils has a first coil end protruding from the radially outermost side of a slot to a first side in the axial direction of the stator core. Each of the three bus bars includes a busbar body portion extending in a circumferential direction of the stator core, a busbar connection portion extending toward the first side in the axial direction, and an external terminal connection portion extending outward in the radial direction and connected to the external terminal. The first coil end extends in the radial direction through between the busbar body portion and the stator core in the axial direction, extends toward the first side in the axial direction on a radially outer side of the busbar body portion, and has a tip connected to the busbar connection portion from the radially outer side.
