BUS BAR MODULE, BATTERY MODULE, AND MANUFACTURING METHOD FOR REUSED BATTERY MODULE

A bus bar module (1) includes a bus bar (10) electrically connect electrode terminals (114) respectively included in a plurality of battery cells (112), and a detection conductor (30) electrically connected to the bus bar (10). The bus bar (10) includes: a pair of electrode joining parts (11) respectively joined to the different electrode terminals (114); a coupling part (12) coupling the pair of electrode joining parts (11) to each other, and capable of being cut between the pair of electrode joining parts (11) where the pair of electrode joining parts (11) is respectively joined to the electrode terminals (114); and a pair of rejoinable parts (13) respectively extending from the pair of electrode joining parts (11). The electrode joining parts (11) and the coupling part (12) constitute a conductive connection part (14) for primary use disposed across the different electrode terminals (114) to electrically connect the different electrode terminals (114) to each other.
