PROBLEM TO BE SOLVED: To provide a moisture-curing hot-melt adhesive composition having isocyanato groups in the molecule, with a sufficient adhesive power even in an uncured state, and free from a defective appearance such as blistering when cured. SOLUTION: The composition consists of 100 pts.wt. crystalline polyester polyol having a melting point measured by a differential scanning calorimeter(DSC) of 30-80 deg.C and 1-30 pts.wt. thermoplastic resin having functional groups reactive with isocyanato groups and having a number-average molecular weight of 7,000 to 50,000 and a softening point measured by the method according to the Japan Adhesive Industry Standard JAI-7-1991 of 150 deg.C or lower, wherein the composition has the terminal functional groups reacted with an isocyanate compound.
