Disclosed herein is a cooling member mounted at a top and/or a bottom of a battery module or a battery pack to remove heat generated from battery cells during charge and discharge of the battery cells, wherein the cooling member includes a thermal conduction member including a stepped fastening plate having step portions of different lengths, coolant flow channels being formed at interfaces of the fastening plate and a coolant conduit configured to have a hollow structure through which a coolant flows, the coolant conduit including a main conduit and one or more branch conduits extending vertically in a state in which the branch conduits communicate with the main conduit such that the branch conduits communicate with the coolant flow channels of the thermal conduction member and wherein mounting grooves corresponding to an external shape of the branch conduits are formed in a relatively long step portion of the fastening plate at ends of the coolant flow channels of the thermal conduction member and auxiliary plates for surrounding outer circumferences of the branch conduits in a state in which the branch conduits are mounted in the mounting grooves are mounted at the fastening plate. |
