A bus bar unit includes a bus bar holder and bus bars. The bus bar holder is provided on an upper side of a stator disposed in a ring around a central axis extending in a vertical direction. The bus bars are supported by the bus bar holder and connected to coil wires extending from the stator. The bus bars are plate-shaped conductors and are supported by the bus bar holder with a plate surface facing in the vertical direction. The bus bars include coil connecting portions connected to the coil wires, and a bus bar body portion connecting the coil connecting portions through a radially inner side of the plurality of the coil connecting portions, respectively, and at least one bus bar crosses over an upper side or a lower side of at least one of the other bus bars.
