1. A moisture-curable hot-melt adhesive composition comprising:
a modified urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having one or more isocyanate groups modified with a castor oil monool; and
a urethane prepolymer, different than the modified urethane prepolymer, including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, having two or more isocyanate groups, and not having an isocyanate group modified with a castor oil monool.
