There is provided a battery pack capable of unfolding support members in the use of an external device having the battery pack joined thereto, and inserting the support members respectively into groove portions in the movement of the external device. The battery pack includes at least one battery cell. A case accommodates the battery cells, and is formed as a portion of the external appearance of an external device. The battery pack further includes groove portions formed in a region at which the battery cells are not positioned in the interior of the case and support members respectively inserted into or protruded from the groove portions. Accordingly, the external device can be more conveniently used, and the external appearance of the external device can be formed slimmer in the movement of the external device. |
