Disclosed herein is a battery module including two battery cells, each of which has electrode terminals formed at upper and lower ends thereof. The battery module further includes a frame member, to which upper-end sealing parts, lower-end sealing parts, and one-side sealing parts of the battery cells are mounted, a metal sheathing member for covering the outer surfaces of the battery cells while the battery cells are mounted to the frame member, and caps (an upper-end cap and a lower-end cap) mounted to the upper and lower ends of the battery cells, respectively, which are covered by the metal sheathing member.
