Zusammenfassung:	To provide a hot-melt adhesive that has good adhesiveness to resin base materials, especially polyolefin base materials such as polypropylene, and also has workability (mold releasability) that allows easy release from a mold.SOLUTION: Provided is a hot-melt adhesive composition that contains a crystalline polyolefin (A) having a Shore A hardness of 80 or more, an amorphous polyolefin (B), and a polypropylene wax (C). The amount of the polypropylene wax (C) is 60 pts.wt. or more to 300 pts.wt. or less based on the total 100 pts.wt. of the crystalline polyolefin (A) and the amorphous polyolefin (B).SELECTED DRAWING: None 【課題】樹脂基材、特にポリプロピレンをはじめとするポリオレフィン基材に対する良好な接着性を有し、併せて金型から容易に剥離できる作業性（金型離型性）も有するホットメルト接着剤の提供。【解決手段】ショアＡ硬度が８０以上である結晶性ポリオレフィン（Ａ）、非晶性ポリオレフィン（Ｂ）及びポリプロピレン系ワックス（Ｃ）を含み、前記結晶性ポリオレフィン（Ａ）と前記非晶性ポリオレフィン（Ｂ）との合計量１００重量部に対し、前記ポリプロピレン系ワックス（Ｃ）の量が６０重量部以上３００重量部以下である、ホットメルト接着剤組成物。【選択図】なし
