Zusammenfassung:	To provide a sealant resin composition that shows greater environmental consideration while maintaining strong adhesion and ease of peeling found in traditional sealant resin compositions made solely from fossil fuel-derived resins.SOLUTION: A sealant resin composition comprises a propylene polymer (A), an ethylenic polymer (B), and at least one kind selected from ethylene-unsaturated carboxylic acid copolymers and ionomers thereof (C). A biomass level of the entire sealant resin composition, measured in accordance with ASTM D6866, is more than 0 mass% and 100 mass% or less.SELECTED DRAWING: Figure 1 【課題】従来の化石燃料から得られる樹脂のみを使用して製造するシーラント用樹脂組成物と同等の接着性と易剥離性を有しつつ、環境配慮性が向上したシーラント用樹脂組成物を提供する。【解決手段】プロピレン系重合体（Ａ）と、エチレン系重合体（Ｂ）と、エチレン・不飽和カルボン酸系共重合体およびそのアイオノマーから選択される少なくとも一種（Ｃ）と、を含むシーラント用樹脂組成物であって、前記シーラント用樹脂組成物全体のＡＳＴＭＤ６８６６に準拠して測定されるバイオマス度が０質量％を超えて１００質量％以下である。【選択図】図１
