PURPOSE: A battery pack is provided to enhance quality reliability by increasing resistivity against external force by improving coupling strength of a bare cell and a frame case. CONSTITUTION: A battery pack comprises a bare cell(110), a circuit module(130) which is electrically connected to the bare cell, a frame case(140) which surrounds the bare cell and comprises channel grooves(148) formed in a region facing the bare cell, and a combination reinforcing part(150) which is formed in the channel groove and connects the bare cell and the frame case'. |
