PROBLEM TO BE SOLVED: To provide a polyurethane resin composition that is excellent in workability at the time of laminating because of low melt viscosity even under low temperature conditions, and excellent in adhesiveness, heat resistance and washing resistance of a laminate, and useful as a hot melt adhesive. I will provide a. SOLUTION: A heat-resistant temperature (Ta) at which a melt viscosity of a thermoplastic polyurethane resin composition is 100,000 Pa · s is in a range of 90 to 140 ° C., and an adhesive temperature (Tb) at which a melt viscosity is 30 Pa · s. ) Is in the range of 130 to 180 ° C, and Tb-Ta is in the range of 10 to 60 ° C.
