A battery module includes; a plurality of battery cell packs; a plurality of heat dissipation plates and a cooler that absorbs heat radiated from the battery cell packs and absorbed by the heat dissipation plates. The battery cell packs and the heat dissipation plates being alternately stacked. Each of the heat dissipation plates has an interlayer plate portion that is in contact with corresponding two of the battery cell packs and side wall plate portions that extend in the stacking direction with respect to the interlayer plate portion on both end sides of the interlayer plate portion and that are in contact with the cooler at outer faces thereof, and each of the heat dissipation plates has a low thermal resistance region between the interlayer plate portion and each side wall plate portion, the low thermal resistance region having a lower thermal resistance than the interlayer plate portion.
