PROBLEM TO BE SOLVED: To provide a moisture-curing type reactive hot-melt adhesive that has excellent initial curability, and can reduce aging time required to e.g. stack adhered articles and until transferring to next working stage. SOLUTION: The moisture-curing type reactive hot-melt adhesive includes an isocyanate-terminated urethane prepolymer obtained by reaction of a polyol composition (A) that includes a polyether polyol (a1) having at least an EO-PO random copolymer structure, a rosin resin polyol (a2) whose hydroxyl value is at least 50, and a polyester polyol (a3), with a polyfunctional isocyanate compound (B).
