PROBLEM TO BE SOLVED: To provide an adhesion method by which a moisture-curable polyurethane hot melt adhesive is not thickened on a roll for a long period and can be cured with moisture in a short time after coated, and to provide a lamination product obtained by the adhesion method. SOLUTION: This adhesion method comprising a process for coating the adhesion surface of at least one of two members to be adhered with a moisture-curable polyurethane hot melt adhesive comprising an amine-based catalyst and a urethane-based prepolymer having a polyester structure portion as a main chain and NCO groups at both the terminals by a roll coater method, and then adhering the two member to each other, is characterized in that the urethane-based prepolymer is a reaction product of a diisocyanate-based compound with a polyester which has OH groups at both the terminals and contains a polyester (A) obtained by reacting a≤C diol having OH groups at both the ends with a dicarboxylic acid having carboxyl groups at both the ends of a≤4C main chain in an amount of≥5 wt.% in all the polyesters.
