<p>A laminate-packaged electric storage device can reliably discharge gas from a specific area without causing leakage of an electrolyte solution when gas is generated inside an outer package. The laminate-packaged electric storage device includes the outer package, an electric storage device element, and the electrolyte solution, the outer package being formed by stacking and seal-tight bonding outer package films along a bonding section that is formed in an outer edge area of each of the outer package films, and the electric storage device element and the electrolyte solution being held in a receiving section that is formed inside the outer package, a non-bonding section that is surrounded by the bonding section and communicates with the receiving section being formed in the outer edge area of each of the outer package films, an opening that is formed through at least one of the outer package films, and a seal section that is formed to surround the opening being formed in an area of the non-bonding section, the outer package films being bonded in the seal section, and the opening being formed in the area of the non-bonding section at a position other than a center position.</p> |
