A bus-bar unit includes bus-bars and a bus-bar holder supporting the bus-bars. The bus-bar includes a first and a second bus-bar piece, including a plate. The first bus-bar piece includes a coil wire connecting portion connected to a coil wire drawn from a stator, and a first junction terminal joined to the second bus-bar piece. The second bus-bar piece includes an external connection terminal connected to an external device, a second junction terminal joined to the first bus-bar piece, and a second piece main body connecting them. The second piece main body has a first extension extending from the external connection terminal along a direction perpendicular or substantially perpendicular to the axial direction, a second extension extending from the second junction terminal along a direction perpendicular or substantially perpendicular to the axial direction, and a crank portion located between them and bent in a crank shape in a plate thickness direction.
