Zusammenfassung:	To provide a hot-melt adhesive having a sufficient laminate strength to vapor-deposited surfaces of a polypropylene film and an aluminum vapor-deposited film or inorganic oxide vapor-deposited film, and a film laminate obtained by laminating the two film base materials using the adhesive.SOLUTION: There are provided a hot-melt adhesive for laminate which contains an asymmetric styrenic block copolymer (A1) and a tackifier resin (B), as necessary, a symmetric styrenic block copolymer (A2); and a film laminate obtained by laminating a first film base material and a second film base material with the hot-melt adhesive for laminate.SELECTED DRAWING: None 【課題】ポリプロピレンフィルム、及びアルミニウム蒸着フィルム又は無機酸化物蒸着フィルムの蒸着面に対して十分なラミネート強度を有するホットメルト接着剤、及び２つのフィルム基材を該接着剤を用いてラミネートしてなるフィルム積層体の提供。【解決手段】非対称スチレン系ブロック共重合体（Ａ１）及び粘着付与樹脂（Ｂ）、さらに必要に応じて対称スチレン系ブロック共重合体（Ａ２）を含むラミネート用ホットメルト接着剤、及び第１のフィルム基材と第２のフィルム基材とを、前記ラミネート用ホットメルト接着剤によりラミネートしてなるフィルム積層体。【選択図】なし
