PROBLEM TO BE SOLVED: To provide an adhesive composition having adhesive force comparable to that of a hot-melt adhesive based on an ordinary styrenic block copolymer in early stages and exhibiting higher adhesive force with the lapse of time, thus excellent in adhesivity and its sustainability. SOLUTION: The adhesive composition comprises a block copolymer(a), a crosslinker(b) and a tackifying resin(c), wherein the block copolymer(a) comprises a styrenic block copolymer bearing respective hydroxy groups on both ends and the crosslinker(b) has in the molecule at least two isocyanate groups.
