Abstract: A bus bar of a bus bar unit includes a main body part extended along a circumferential direction of the stator such that a plate thickness direction of the bus bar agrees with an axial direction of the stator; an extension part extended from the main body part in a radial direction of the stator; and a coil connection part provided at a tip of the extension part, the coil connection part being connectable to a winding terminal of the coil. The extension part includes a retained part having surfaces perpendicular to the axial direction of the stator on both sides of the plate thickness direction. The retained part are held by molds for the insert molding of the bus bar when the insulating resin is formed by the insert molding of the bus bar.
