Abstract
A battery module has a cell unit including battery cells, a positive external terminal electrically connected to a positive side of the battery cells through a positive electro conductive member, and a negative external terminal electrically connected to a negative side of the battery cells. The positive electro conductive member extends a first surface which is one of surfaces of the cell unit. The negative electro conductive member extends of a second surface which is one of surfaces of the cell unit other than the first surface.
