A battery module includes a plurality of rectangular cells, holders, first and second end plates and joining members. The joining members join the first and second end plates to fasten the plurality of rectangular cells and the holders to be a single unit. Ends of the joining members are fastened to first securing parts and second securing parts on the first and second end plates. The first securing parts and the second securing parts are disposed at both ends of a center line that penetrates through centers of the plurality of rectangular cells, the holders, and the first and second end plates. A distance between the center line and each of the first and second securing parts is smaller than a distance between each of the first and second securing parts and each of outermost surfaces of the first and second end plates.
