To provide an excellent multilayer structure which indicates an excellent gas barrier property as a whole of the multilayer structure and in which an ethylene-vinyl alcohol-based copolymer layer is less likely to be affected by ingress of water even immediately after retort processing.SOLUTION: A multilayer structure comprises an ethylene-vinyl alcohol-based copolymer layer (A), an adhesive resin layer (B), and a cyclic olefin-based resin layer (C) laminated on the ethylene-vinyl alcohol-based copolymer layer (A) via the adhesive resin layer (B). The ethylene-vinyl alcohol-based copolymer layer (A) contains a desiccant (D).SELECTED DRAWING: None
