Abstract
A battery pack 100 has plural battery modules 110 each of which constituted with plural unit cells 120 arranged in a row. Furthermore, a spacer 130 intervenes between adjoining battery modules 110 to constitute a cooling passage 160 which makes cooling medium flow and cools down the unit cells 120. The spacer 130 is designed to flow the cooling medium in a row direction of unit cell cases 121 integrated in a battery module 110. The spacer 130 is structured such that touch area of the cooling medium and the unit cell cases 121 becomes lager as going from inlet side to outlet side of the cooling passage 160 with respect to each of the plural battery modules 110.
