To provide a moisture-curable hot-melt adhesive agent having excellent balance of initial adhesive strength, adhesive strength after curing and heat resistance and the like, and a layered product bonded with the moisture-curable hot-melt adhesive agent. Means for solving the problem: A moisture-curable hot-melt adhesive agent comprising an urethane prepolymer having an isocyanate group at the end (A), a styrene based block copolymer (B), and a tackifying resin (C), wherein the styrene based block copolymer (B) comprises a styrene based block copolymer having 10 to 35% by weight of a styrene content (B1) and a styrene based block copolymer having 40 to 70% by weight of a styrene content (B2). |
