A battery pack including a case, which is improved by preventing deformation, such as warp, from occurring to the case, is provided. The battery pack includes one or more batteries, a protective circuit module (PCM) electrically connected to the batteries, a case accommodating the batteries and the PCM, and one or more warp preventing portions inserted into a frame forming the case and formed along the lengthwise direction of the case. Accordingly, it is possible to prevent the case of the battery pack from being warped or distorted. |
