PROBLEM TO BE SOLVED: To obtain a hot-melt adhesive composition showing extremely excellent adhesion performances of so-called hardly bondable materials such as polyolefin materials, for example, polypropylene and polyethylene which have been difficult to bond, since extension in the application range of hot-melt adhesives and a hot-melt adhesive showing excellent adhesion performances have been required. SOLUTION: This hot-melt adhesive composition comprises 5-50 wt.% of (a) an ethylene-vinyl acetate copolymer, 5-50 wt.% of (b) a saponified substance of ethylene-vinyl acetate copolymer, 5-50 wt.% of (c) an ethylene-acrylic acid ester copolymer, 5-40 wt.% of (d) a tackifier resin and <=8 wt.% of (e) an amide wax.
