Abstract
A bus bar assembly includes bus bars and a bus bar holder that is made of an insulating material and holds the bus bars in a non-contact state. The bus bars include base portions that overlap with other bus bars in the axial direction, and connecting portions extending from the base portions along the radial direction. At least two of the bus bars include stepped portions extending toward the other bus bars between proximal ends of the connecting portions and connection ends connected to windings. The bus bar holder molds the base portions and the stepped portions in a state where the connection ends are exposed.
