The invention provides a moisture-curable hot melt adhesive which has good setting strength and enough long bonding time. The moisture-curable hot melt adhesive is a moisture-curable hot melt adhesive containing an alkoxysilyl group-containing urethane prepolymer (A) represented by general formula (a). The moisture-curable hot melt adhesive is characterized in that: the moisture-curable hot melt adhesive contains an alkoxysilyl group-containing urethane prepolymer (A) represented by general formula (a); in general formula (a), Y represents a residue obtained by removing-O-C (= O)-NH-A-NCO from an isocyanate group-terminated urethane prepolymer (a1), which is a reaction product of a diisocyanate (i) and a polyol (ii) (wherein A represents a residue obtained by removing two isocyanate groups from a divalent diisocyanate, and Y represents a residue obtained by removing-O-C (= O)-NH-A-NCO from an isocyanate group-terminated urethane prepolymer (a1). W represents a residue obtained by removing ...
