To provide a battery module capable of reducing a space necessary for connecting batteries to one another.SOLUTION: A battery module comprises a plurality of batteries and a bus bar for electrically connecting the plurality of batteries to one another. The battery comprises: a battery can having a cylinder part, a bottom wall which closes one end portion of the cylinder part, and an opening edge continuous to the other end of the cylinder part; an electrode body housed in the cylinder part; and a sealing body fixed at the opening edge in a manner to sela the opening of the opening edge and having a first main face directed to inside of the battery can, a second main face located on an opposite side to the first main face, and a side face coupling the first face and the second face. The bus bar has a plurality of though holes for fitting the batteries. At least a portion of the opening edge of the battery fitted into the through hole comes into contact with the bus bar. The opening edge and the bus bar are electrically connected to each other. The sealing body and the bus bar are electrically insulated.SELECTED DRAWING: Figure 1A 【課題】電池同士を接続するために必要な空間を小さくすることができる、電池モジュールを提供する。【解決手段】複数の電池と、複数の前記電池を電気的に接続するバスバーと、を備え、前記電池は、筒部、前記筒部の一方の端部を閉じる底壁および前記筒部の他方の端部に連続する開口縁を有する電池缶と、前記筒部に収容された電極体と、前記開口縁の開口を封口するように前記開口縁に固定され、前記電池缶の内側を向く第１主面、前記第１主面とは反対側の第２主面、および、前記第１主面と前記第２主面とを繋ぐ側面を有する封口体と、を備え、前記バスバーは、前記電池を嵌め込む複数の貫通孔を備えており、前記貫通孔に嵌め込まれた前記電池の前記開口縁の少なくとも一部は、前記バスバーと接触し、前記開口縁と前記バスバーとは、電気的に接続されており、前記封口体と前記バスバーとは、電気的に絶縁されている、電池モジュール。【選択図】図１Ａ
