Zusammenfassung:	A manufacturing method of manufacturing a battery pack that includes: a cell group obtained by stacking unit cells in a stacking direction, and a bus bar electrically connecting the unit cells. Each of the unit cells has a cell body, an electrode tab and a spacer. The electrode tabs protrude out from the cell bodies, and are supported by the spacers. The method includes positioning joining portions of the electrode tabs to the bus bar at predetermined positions in a movement direction of the spacers by moving the spacers in one direction in a state in which the unit cells and the spacers are stacked, before the bus bar is joined to the electrode tabs. In addition, the method includes joining the bus bar to the electrode tabs in a state in which the joining portions of the electrode tabs are positioned at the predetermined positions.
