A battery pack is provided to prevent short-circuit of a battery which can be generated in a welding process without the need of welding and soldering process and to minimize resistance change of the connecting area. A battery pack comprises connection members(100,102) which electrically connect a plurality of secondary battery cells(302,304,306) mounted on a receiving portion of a pack case(200) which does not have partition. The connection members is positioned between battery cells arranged in a longitudinal direction or a longitudinal direction and width direction and is connected to the lower electrode terminal of a preceding battery cell and/or the upper electrode terminal of a following battery cell, by using a mechanical connection manner. |
