A method for producing a laminated body including a base material and a coating layer laminated on the base material, includes: applying a coating liquid containing cellulose nanofibers onto the base material composed of at least acid-resistant paper, thereby forming the coating layer. In addition, an average fiber diameter of the cellulose nanofibers is 2 nm or more and 2000 nm or less, a content of the cellulose nanofibers in the coating liquid is 10 mass % or more of solid contents of the coating liquid, and a coating amount of the coating layer is 0.2 g/mor more in dry mass.
