A moisture-curable polyurethane hot melt adhesive containing a urethane prepolymer obtained by reacting a polyol and a polyisocyanate is characterized in that the polyol contains a long-chain aliphatic polyester polyol (A) represented by the general formula (I) below, an aliphatic polyether polyol (B) having a number-average molecular weight of 3,000-15,000, and an aromatic polyester polyol (CI) having a number-average molecular weight of 1,000-5,000 and a glass transition temperature of not less than 40 DEG C. In the general formula (I), R<1> and R<2> independently represent a straight chain alkylene group having an even number of carbon atoms, and the total number of carbon atoms in R<1> and R<2> is not less than 12; and n represents a number of 3-40. |
