Disclosed herein are a connection member for electrically interconnecting a plurality of battery cells in a battery pack in which the battery cells are mounted, wherein the connection member includes at least two terminal contact parts, which are connected to electrode terminals of neighboring battery cells, and a connection part for interconnecting the terminal contact parts, and wherein the terminal contact parts are lower in height, by a size corresponding to the thickness of a pack case, than the connection part such that the connection member connects the electrode terminals of the battery cells while the connection member is mounted on the outer surface of the pack case, and a battery pack including the same. Consequently, the connection member according to the present invention has the effect of effectively interconnecting the electrode terminals of the battery cells through a simple assembly process. Also, the connection member according to the present invention can be directly mounted on the pack case without using an additional auxiliary member.
