PROBLEM TO BE SOLVED: To reduce conductive materials and members of a bus bar unit.SOLUTION: A bus bar unit comprises: three first bus bars 5a, 5b, 5c to which one-side ends of lead wires of three coil groups are connected and which include external connecting terminals 51; a second bus bar 5d for a neutral point to which other-side ends of the lead wires are connected; and a resin holder which holds the three first bus bars and the second bus bar. The external connecting terminals of the three first bus bars are disposed while being collected in one area in a circumferential direction around a central axis, the three first bus bars and the second bus bar are overlapped only in a radial direction or an axial direction around the central axis, and the number of overlapped bus bars is two at a maximum. |
