摘要：
A laminate having high adhesion between a fine cellulose layer and a base material, a method for producing the 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 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 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. The laminate may also be produced by providing a swollen base material, coating the swollen base material with a dispersion containing fine cellulose having a carboxyl group, and drying the base material and the coated dispersion.
