PROBLEM TO BE SOLVED: To obtain a hut-melt adhesive composition containing a specific ethylene-α-olefin copolymer, styrene-ethylene-propylene-styrene block copolymer and an adhesiveness imparting agent, and suitable for assembling a hygienic material such as a diaper. SOLUTION: This hot-melt adhesive composition contains (A) ethylene-α-olefin copolymer having <=0.90g/cm<3> density, (B) a styrene-ethylene-propylene-styrene block copolymer and (C) an adhesiveness imparting agent. Also, it is preferable to contain (D) a plasticizing oil. Further, as the content of each of the components, 10-80wt.% component (A), 1-50wt.% component (B) and 19-60wt.% component (C) are preferable. Also, in the component (B), the content of styrene is preferably 10-35wt.%.
