Kind Code:

A1

Abstract:

[Problem] To provide an assembled battery for which it is possible to easily adjust the position of and to join a plurality of bus bars and a plurality of electrode tabs, a bus bar holder used for the assembled battery, and a method for manufacturing the assembled battery. [Solution] The present invention has: a plurality of unit cells 110 that have an electrode tab 112; a plurality of spacers 114 that have a striking surface 114h with which the electrode tab 112 makes contact; a plurality of bus bars 132 that have a surface 132f where contact is made by the spacer joined to the electrode tab 112, the contact surfaces of the bus bars 132 facing the contact surfaces of the spacers with the electrode tab interposed therebetween; and a bus bar holder 131 that has a holding part 131d that holds the plurality of bus bars. The bus bar holder further has a pressing part 131k that presses the bus bars held in the holding part from a pressed surface 132e that is on the side of the spacer opposite the contact surface, facing the striking surface.
