PROBLEM TO BE SOLVED: To provide an assembled battery that improves the ease of fixing bus bars by preventing battery modules from short-circuiting while the bus bars are fixed.SOLUTION: The assembled battery includes: a battery module group comprising a plurality of battery modules arrayed such that positive and negative output terminals are led out in the same direction; a plurality of conductive bus bars 40 fastened to the positive and negative output terminals by bolts 43 passed through bolt holes 41 to electrically connect the battery modules together; and a single bus bar holding plate 20 in the shape of a plate formed from an insulating material arranged only in the lead direction of the positive and negative output terminals to hold all the bus bars integrally. The assembled battery further includes insulating barrier projection parts 170 positioned only between the plurality of bus bars exposed on a bus bar holding surface 20a and corresponding proximate bus bars, and projecting beyond the surfaces of the bus bars opposite to the battery module group. The insulating barrier projection parts serve as barriers against short circuits of the bus bars. |
