The present invention provides a battery pack that does not increase contact resistance when an impact is applied to a bare cell and a protection circuit module. The battery pack includes: a bare cell having a surface on which at least one coupling groove is formed; a protection circuit module electrically connected to the bare cell; a coupling member having one end coupled to the protection circuit module and another end in which a coupling hole corresponding to the coupling groove of the bare cell is formed, and tightly adhered to the bare cell; a screw bolt coupled to the coupling groove through the coupling hole; and a space formed in an opening part of the coupling groove, having a diameter greater than that of the coupling groove. Therefore, the battery pack does not increase the contact resistance between the bare cell and the protection circuit module against an external impact. |
