It is intended to provide a battery module having a long life by designing such that deterioration proceeds evenly among battery cells. Disclosed is a battery module including a plurality of battery groups being connected in series and each comprising a plurality of battery cells connected in parallel, wherein: a positive electrode terminal and a negative electrode terminal are provided; the battery groups are connected to each other by a plurality of electrically conductive strips; and an electrical resistance value of the conductive strip arranged at a position near a virtual line drawn between the positive electrode terminal and the negative electrode terminal is high, and an electrical resistance value of the conductive strip arranged at a position other than the position near the virtual line is low, the electrical resistance value being measured in a direction of charge and discharge current flow. |
