A battery pack is provided to form the thin thickness of an outer case regardless of moldability and material characteristic which are a technical restriction condition of an injection molding method, and to enhance the resistivity against twisting. A battery pack includes a rechargeable bare cell(10); a circuit member(20) which is arranged at the upper part of the bare cell, and is electrically connected to the bare cell; a frame case(30) covering the bare cell including the circuit member, which is formed to expose the long side facing the bare cell; and a thin film sheet(40) combined with the frame case to cover the long side of the bare cell. |
