Each of busbars of a busbar unit includes a main body part that extends along a circumferential direction of the stator so that a plate thickness direction coincides with an axial direction of a stator; a projecting part that projects radially outwardly of the stator from outer periphery of the main body part; an extending part bent from the projecting parts, the extending part extending in the axial and radial direction of the stator; and a connecting part provided on a tip of the extending part, the connecting part being connectable to the winding wire ends of the coils. A position of the connecting part is specified in accordance with length of the extending part in the axial and radial directions of the stator.
