PROBLEM TO BE SOLVED: To provide a battery pack in which electrode terminals of unit batteries arranged adjacent to each other can be simply and easily connected without giving an unusual force to the electrode terminals and the electrode terminals with potential differences arranged close to each other are surely insulated to prevent a short-circuit current from flowing to unit batteries. SOLUTION: The battery pack includes a plurality of unit batteries 10 arranged adjacent to each other. The neighboring unit batteries 10 are connected with electrode terminals 11 by a connecting piece 12. Moreover, the battery pack includes an insulation holder 13 having an electrode coupling portion 20 for connecting with the electrode terminals 11. The insulation holder 13 has a connection piece holding portion 21 for arranging the connecting piece 12 at a constant position and connects the electrode terminals 11 of the neighboring unit batteries 10 by the connecting piece 12 arranged with the connecting piece holding portion 21 at the constant position.
