This bus bar module (26) is created by integrally forming at least one coil bus bar with a power line bus bar by means of resin molding, said coil bus bar for connecting conductive coil wires together, and said power line bus bar for connecting the conductive coil wires with a power line. The power line bus bar (32) is supported on a support portion (34) that extends from a bus bar module main body (28). The power line bus bar penetrates through a beam (44) of the support portion. The portion of the power line bus bar embedded inside the beam (44) has characteristically shaped portions (56) extending in the width direction of this bus bar.
