PROBLEM TO BE SOLVED: To aim at the provision of an adhesive composition hardly receiving the effect of moisture and inhibiting the foaming of carbon dioxide, and especially, on pasting a gas barrier type films with each other, provide a two-liquid type adhesive for urethane lamination capable of inhibiting an inferior appearance accompanying with the generation of gas and the lack of strength. SOLUTION: This two-liquid type adhesive for lamination used for bonding the films of a laminated sheet is provided by using as blending an isocyanate with a polyurethane polyol having a specific molecular terminals within (the number of hydroxy groups)/(the number of the isocyanate groups)=(1/0.5) to (1/1.5) range, desirably by (1/0.5) to (1/0.9) range.
