Disclosed is a battery module. The disclosed battery module comprises: battery cells; a busbar holder which is disposed on an upper part of the battery cells, and in which several busbar to electrically connect the battery cells is mounted; and a circuit substrate which is disposed on the upper part of the busbar holder, and on which a component to control and monitor the state of charging or discharging the battery cells is mounted, wherein the circuit substrate includes a plurality of coupling holes formed along a peripheral part, and is fixed in the busbar holder by several coupling members coupled by the busbar holder through a part of the coupling holes (first coupling holes) among the plurality of coupling holes. According to the present invention, after assembling the circuit substrate on which the important component of the battery module is mounted, random disassembly thereof can be prevented. |
