<p>PROBLEM TO BE SOLVED: To solve such a problem that a dead space is liable to be formed between a power storage element and a substrate when a duct is disposed between the power storage element and the substrate.SOLUTION: A power storage device (1) includes a plurality of power storage elements (10) which are arranged side by side in a predetermined direction (X direction). Each of the power storage elements includes a valve (13) that discharges gas generated within the power storage element to the outside of the power storage element. Bus bars (31) are connected to electrode terminals (11, 12) of the power storage elements, and the plurality of power storage elements are electrically connected by the bus bars. The electrode terminal penetrates a substrate (40) on which an electronic component is packaged, and in the substrate, an opening (41) is formed through which the gas discharged from the valve passes. The power storage device includes a duct (50) that the gas having passed through the opening of the substrate enters, and the duct is disposed at a position away from the electrode terminal protruding from the substrate.</p> |
