Zusammenfassung:A hot melt adhesive composition which can realize moderate adhesive strength with respect to the adherend when porous substrate is used, is provided. A hot melt adhesive composition, including: a styrene-based block copolymer; a tackifier; and a plasticizer; wherein: the styrene-based block copolymer is a styrene-butadiene block copolymer and a butadiene portion thereof is partially hydrogenated; the tackifier is contained by 65 to 190 parts by mass with respect to 100 parts by mass of the styrene-based block copolymer; and the plasticizer is contained by 0.1 to 24 parts by mass with respect to 100 parts by mass of the styrene-based block copolymer, is provided.
