A middle and large-sized battery module is provided to improve productivity and reliability by safe and easy fastening of battery cells and to prevent short circuit due to the separation of battery cells. A middle-sized battery module(400) comprises the structure where at least two plate-like battery cells(200,202,204,220,222,224) which are arranged in width direction. The battery cells are arranged so as to allow electrode terminals(212,214) to toward the same direction. The plate-like electrode terminal connecting members(100) for the electrical connection of the battery cells are electrically combined on the orientation plane of the battery cell electrode terminals. The structure for the mutual fastening of connecting members is formed on the upper and/or lower surface of the electrode terminal connecting members, and the one terminal part or both terminal parts of the insulating joint member(150) combined to the fastening structure are supported by a module case. |
