Provided are a laminate which has high adhesion between a fine cellulose layer and a base material and is thus less likely to undergo delamination and a method for producing same, and a gas barrier material. The laminate is such that a fine cellulose layer containing fine cellulose having a carboxyl group is laminated on one or both surfaces of the base material, and a mixed layer in which the fine cellulose is mixed in the base material is further interposed between the base material and the fine cellulose layer. This laminate can be produced by coating one or both surfaces of the base material with a dispersion containing fine cellulose having a carboxyl group, swelling the base material with the thus coated dispersion, and drying the swollen base material and the coated dispersion. Alternatively, the laminate may also be produced by providing a swollen base material, coating one or both surfaces of the swollen base material with a dispersion containing fine cellulose having a carboxyl group, and drying the base material and the coated dispersion. |
