PROBLEM TO BE SOLVED: To provide a battery pack.SOLUTION: The battery pack includes: a plurality of battery cells; a case frame having an opened end so as to receive the battery cells; and a finishing plate assembled to the opened one end part of the case frame. The case frame includes: a pair of side plates extending in an arrangement direction of the battery cells so as to cover both lateral faces of the battery cells; and an end plate forming the other closed end part between the pair of side plates. The paired side plates and the end plate are formed integrally. Thereby, the battery pack has a coupling structure improved so as to exhibit a sufficient coupling strength while facilitating an assembling step in a process of assembling two or more battery cells into a module. |
