An object of the present invention is to provide a resin composition excellent in gas barrier properties after hot water treatment, and in a melt-kneading process at the time of molding, in which the viscosity of the resin composition does not increase and excellent in handleability, and at least one layer of the resin composition. A multilayer structure having layers is provided. A resin composition containing a partially dehydrated product or a completely dehydrated product (B) of a thermoplastic resin (A) and a carboxylate hydrate. The content ratio A / B is 10/90 to 99/1 by weight. The thermoplastic resin (A) contains 1 to 40% by weight of a polyamide-based resin with respect to the saponified ethylene-vinyl ester polymer and the saponified product. [Selection figure] None |
