により積層されていることを特徴とする積層体。 A gas barrier layer made of ethylene/vinyl alcohol copolymer is laminated on one surface of a foamed polystyrene sheet with an expansion ratio of 2 to 10 times, and a heat-sealable sealing layer is laminated in this order, between the foamed polystyrene sheet layer and the gas barrier layer. The adhesive layer has a two-layer structure, starting from the foamed polystyrene sheet layer: a layer containing a butadiene-styrene copolymer, and a layer containing a resin composition consisting of an ethylene-vinyl acetate copolymer and an ethylene-vinyl alcohol copolymer. A laminate characterized by being laminated.
