Provided is a secondary battery module, which shows a high capacity from a plurality of unit cells connected to each other, and has a simplified connection structure to reduce the time and labor required to perform the connection or exchange of unit cells. The secondary battery module comprises a plurality of unit cells(11) and a connection member(50) electrically connected between one terminal(14) and another terminal(15). In the secondary battery module, the connection member comprises: an outer portion(52) having a through hole(51) so that it is inserted to a terminal; an intermediate portion(53) having a smaller thickness as compared to the outer portion and connecting a gap between one outer portion and another outer portion; and a channel-like groove(54) formed on at least one surface of the intermediate portion. |
