Laminate-packaged electric storage device

Even if the inside of the body to provide an exterior gas is generated, it is possible to laminate non-packaged electric storage device reliably discharge the gas leakage from specific portions. Outside of the laminate-packaged electric storage device having an outer casing, at the junction of the outer package body is formed in the respective outer peripheral portion through an exterior film overlapping mutually hermetically joined to form, the housing portion is formed in the inside of the exterior body the respective outer peripheral portion of the stored electric storage device element and an electrolyte solution, constituting the outer thin film outer package body overlap each other is formed with a non-bonding, the non-bonding is bonding encloses and communicates with the accommodating portion, is formed of a non- region joint portion is formed in an aperture, and a sealing portion, through the aperture portion of one of the exterior film, the sealing portion is formed to surround at least a portion of the aperture, and the sealing portion is formed by engaging an exterior portion of each film, the hole the mouth portion is formed at a position other than the center is formed with a non-bonding position of the region in.
