PURPOSE: A battery pack is provided to simplify a manufacturing process of an outer case since an insulating tape is unnecessary, to reduce the number of components, and to enhance resistivity to twisting. CONSTITUTION: A battery pack includes: a rechargeable bare cell; a circuit member(20) electrically connected to the bare cell; and a frame case(30) covering the outside whole except for a pair of long side portions of the bare cell. A round undercut(30g) is formed on one inner surface of the frame case in which the bare cell is mounted. One side portion of the bare cell is forcedly inserted in the undercut. |
