BATTERY PACK

PROBLEM TO BE SOLVED: To make joining easy when electrode terminals are mutually connected.SOLUTION: A battery pack includes: a pair of end plates 20 to respectively cover the end face of a battery laminate 1 in which a plurality of unit cells 10 are laminated in a thickness direction; and a bind bar 22 to connect the pair of end plates 20. Furthermore, as for respective unit cells 10, a holder body 30 to couple a plurality of connecting holders 31 are equipped which are inserted between the end face of the unit cells 10 and a bent piece 12, and in which a holder screw hole for coupling a terminal fixing screw 36 is opened at a position corresponding to a terminal screw hole 13 of the bent piece 12. The holder body 30 separates respective connecting holders 31 mutually in parallel by its spacing corresponding to the spacing of respective laminated unit cells, and furthermore, one end part of the respective connecting holders 31 is respectively fixed by a connecting piece 32.
