PROBLEM TO BE SOLVED: To provide a battery module capable of highly accurately detecting voltage of battery cells constituting a battery stack.SOLUTION: There is provided a battery module comprising: a battery stack in which a plurality of battery cells are laminated; a substrate arranged on an upper surface of the battery stack; battery monitoring means mounted on the substrate and for monitoring a battery cell state; and a bus bar formed by processing a metal wire and connecting the electrodes of the battery cells and the substrate. The bus bar comprises a bus bar part having a long hole shape in which a lamination direction of the battery stack is a long side or a long diameter and including an insertion hole into which the electrode is inserted, and a lead-out part connecting the bus bar part and the substrate. The lead-out part comes into contact with a fastening part fastening the electrode and the bus bar part. |
