Summary:To provide a technique capable of reducing the size of a bus bar unit having a conductive member and a resin bus bar holder in the axial direction.SOLUTION: A bus bar unit 6 includes a plurality of conductive members 61, and a resin bus bar holder 62 that holds the plurality of conductive members. The conductive member has a plate-shaped portion 611 extending perpendicular to the central axis. The plurality of plate-shaped portions are arranged so as to overlap each other in the axial direction. At least a part of the upper surface of an upper plate-shaped portion 611c located at the uppermost stage among the plurality of plate-shaped portions is exposed from the bus bar holder. Therefore, the bus bar unit can be miniaturized in the axial direction as compared with a case in which the entire upper surface of the upper plate-shaped portion is covered with the bus bar holder.SELECTED DRAWING: Figure 5 【課題】導通部材と樹脂製のバスバーホルダとを有するバスバーユニットを、軸方向に小型化できる技術を提供する。【解決手段】バスバーユニット６は、複数の導通部材６１と、複数の導通部材を保持する樹脂製のバスバーホルダ６２とを有する。導通部材は、中心軸に対して垂直に広がる板状部６１１を有する。複数の板状部は、軸方向に重なって配置される。複数の板状部のうち、最上段に位置する上段板状部６１１ｃの上面の少なくとも一部分は、バスバーホルダから露出している。このようにすれば、上段板状部の上面の全体がバスバーホルダに覆われている場合と比べて、バスバーユニットを軸方向に小型化できる。【選択図】図５
