A method of producing a laminated body, the method including a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body, the metal salt is a polyvalent metal salt. In the method of producing a laminated body, the organic acid is an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group.
