A battery pack includes a battery cell; a lower case having an opening and a space housing the battery cell; an upper case coupled to the opening of the lower case and having a first coupling hole formed therein; a first lead tab having opposing sides coupled to the upper case, a central region between the opposing sides contacting an interior-facing surface of the upper case and having a second coupling hole, and an intermediate region between each of the opposing sides and the central region, the intermediate region being spaced from the interior-facing surface of the upper case; and a coupling unit coupling the first lead tab to the interior-facing surface of the upper case and penetrating the first coupling hole and the second coupling hole.
