    摘要： In an integrated sealed secondary battery (1) in which a plurality of cells (2) are arranged in a row, cooling medium passages (21) are formed on both sides of the row of the cells (2), and cooling medium passages (18) are formed between adjacent cells such as to effect communication between the cooling medium passages (21,21) on both sides. The cross-sectional areas of the cooling medium passages (21,21) on both sides are made different so as to generate pressure difference at both ends of the cooling medium passages (18) between the cases. The cooling medium passages (21) on both sides are formed in a meandering manner by the provision of projection strips that extend alternately downwards from the top wall and upwards from the bottom wall of the cooling medium passages (21).
    Air escape apertures (43) are formed between the top wall (42) of the cooling medium passages (21) and top ends (41a) of the projection strips (41) that extend downwards from the top wall of the cooling medium passages.
