    • PROBLEM TO BE SOLVED: To provide a method for producing a cellulose nanofiber laminate having excellent gas barrier property by enhancing the orientation of cellulose nanofibers.SOLUTION: The method for producing a cellulose nanofiber laminate includes: a step S10 for processing a pattern having a groove shape in at least one surface of a base material; a step S20 for coating the processed surface with a coating liquid containing cellulose nanofibers; and a step S30 for drying the coating film formed by coating of the coating liquid to form a cellulose nanofiber layer. In the step S10 for processing the pattern having a groove shape in the base material, the pattern is formed by pressing a groove mold against the base material, and the groove shape is a V-groove shape having a width of 0.1-0.5 μm and a depth of 0.1-0.5 μm. Further, the method includes a step for forming a vapor deposition layer composed of an inorganic compound and a step for forming a thermoplastic resin layer.
