A multilayer structure includes an adhesive resin layer provided between a thermoplastic resin layer and a gas barrier resin layer, wherein the adhesive resin layer is formed from a resin composition containing a polyolefin resin (A) containing at least one of a carboxyl group and an acid anhydride group, and a fatty acid zinc salt (B), wherein the fatty acid zinc salt (B) is present in the resin composition in a proportion of 40 to 250 ppm on a metal basis based on the amount of the adhesive resin layer. The multilayer structure has a higher level of transparency, because interface roughness in an interface between the gas barrier layer and the adhesive resin layer is significantly suppressed. |
