Zusammenfassung: | [PROBLEM] To provide a manufacturing method of a battery pack, whereby an electrode tab and a bus bar can be suitably joined. [SOLUTION] The method comprises an electrode tab positioning step for positioning a joining portion of the electrode tab on the bus bar at a predetermined position, in a movement direction of the first spacer, by moving the first spacer in one direction in a state in which the unit cells 110 and the first spacer 121 are stacked, before the bus bar 131 is joined to the electrode tab 113, and a joining step for joining the bus bar to the electrode tab, in a state in which the joining portion of the electrode tab is positioned at a predetermined position. |
