(57) [Problem] To provide a gas barrier film using a polyvinyl alcohol-based resin as a gas barrier layer and having excellent gas barrier properties even under a high humidity exceeding 90% RH. SOLUTION: This is a laminate including a base layer made of a thermoplastic resin film and a gas barrier layer made of a hydrolyzate of silicon alkoxide, a layered silicate and a polyvinyl alcohol resin, and is measured by light scattering in the gas barrier layer. The radius of rotation (Rg) of the obtained scatterer is 2.4 μm or less, and silicon alkoxide and / or a hydrolyzate thereof exist between the layered silicates present in the gas barrier layer. |
