PROBLEM TO BE SOLVED: To provide a laminate in which deterioration with time of a substrate and a layer of cellulose nanofibers can be suppressed.SOLUTION: The laminate includes at least: a substrate 1; and an anchor layer 2 and a layer 3 of cellulose nanofibers having a carboxyl group, which are provided in this order on one surface of the substrate 1. The anchor layer 2 contains at least one resin having a carboxyl group, a sulfonic acid group, an amino group, or a hydroxyl group. The cellulose nanofibers are an oxidized cellulose into which a carboxyl group has been introduced by an oxidation reaction, and the content of the carboxyl group is 0.1 to 5.5 mmol/g inclusive. |
