Disclosed is a battery pack that enables its outer case to be formed in small thickness regardless of formability and material property, and has enhanced twisting resistance. The battery pack includes a bare cell for generating electricity, a circuit member provided at an upper part of the bare cell and electrically coupled to the bare cell, a frame case formed so as to expose front and back parts of the bare cell externally while covering the bare cell including the circuit member, and a film sheet connected to the frame case so as to cover the front and back parts of the bare cell.
