Summary: | The present invention provides the following, etc., as resin compositions having excellent gas barrier properties, especially oxygen barrier properties, under high humidity conditions. A resin composition including a hydrophilic resin and a metallic compound, the resin composition being characterized by satisfying formula (1) when made into a film. (1): alpha - beta >= 1, where alpha represents the average metal atom concentration (%) within a depth of 0-9 nm from the surface of the film, and beta represents the average metal atom concentration (%) within a depth of 12-21 nm from the surface of the film.
