BUS BAR MODULE

摘要

A bus bar module includes a holding member for holding the plural bus bars with a mutual distance between the bus bars maintained. The holding member includes a first holding member for holding the plural bus bars in one electrode line of the plural battery cells, a second holding member for holding the plural bus bars in the other electrode line of the plural battery cells, and a joining member for structurally joining the first holding member to the second holding member. The joining member is formed in an arch shape upwardly projected from inside ends of the first holding member and the second holding member. The joining member has a rigid part adapted to maintain the arch shape and a flexible part adapted to vertically bend by a load from above.
