Provided is a sealed container capable of stably obtaining a high barrier performance. A receiving portion (16) is formed in the sealed container by overlapping laminate packaging members (10a, 10b), in which a thermoplastic resin layer (14) is laminated on at least one surface of a barrier layer (13), while the thermoplastic resin layer (14) is used as an inside, and then bonding peripheral portions of the overlapping laminate packaging members (10a, 10b) to each other, and then sealing. A sealing part (31) of the peripheral portion has: a heat seal part (33) on which the thermoplastic resin layer (14) is fused; and a plurality of barrier layer bonding portions (34) where the barrier layers (13) are bonded to each other. The plurality of barrier layer bonding portions (34) is disposed in the heat seal part (33) in a spot shape, such that they are not continuous. |
