The gas barrier laminate includes a base material, and a gas barrier layer provided on at least one side of the base material. The gas barrier layer contains at least cellulose fibers and one or more kinds of water-soluble polymer. Additionally, the fiber width of the cellulose fibers falls within a range of 3 nm to 50 nm.
