Abstract
In an integrated sealed secondary battery in which a plurality of cells are arranged in a row, cooling medium passages are formed on both sides of the row of the cells and cooling medium passages are formed between adjacent cells such as to effect communication between the cooling medium passages on both sides. The cross-sectional areas of the cooling medium passages on both sides are made different so as to generate pressure difference at both ends of the cooling medium passages between the cases. The cooling medium passages 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
