Zusammenfassung:To provide a decorative sheet and a decorative material which reduce a used amount of fossil fuel by using a plant-derived material, and can maintain physical property suitable for application as the decorative sheet.SOLUTION: A decorative sheet 1 includes a colored base material layer 2, a pattern layer 3, an adhesive resin layer 4, and a transparent resin layer 5, in this order, where the colored base material layer 2 and the transparent resin layer 5 are each a resin layer formed of a resin composition containing biomass-derived polyolefin polymerized with a monomer containing biomass-derived olefin, the transparent resin layer 5 contains 5 mass% or more of the biomass-derived olefin, and has density of 0.92 g/cm3 or more and 0.99 g/cm3 or less, the colored base material layer 2 contains 5 mass% or more of the biomass-derived olefin, and has density of 0.92 g/cm3 or more and 1.12 g/cm3 or less, and the pattern layer 3 contains a coloring agent and a biomass-derived component.SELECTED DRAWING: Figure 1 【課題】植物由来の材料を用いることで化石燃料の使用量を削減し、且つ化粧シートとしての用途に適した物性を維持することが可能な化粧シート及び化粧材を提供する。【解決手段】本実施形態に係る化粧シート1は、着色基材層2と、絵柄層3と、接着性樹脂層4と、透明樹脂層5とをこの順に備え、着色基材層2及び透明樹脂層5は、それぞれ、バイオマス由来のオレフィンを含むモノマーが重合したバイオマス由来のポリオレフィンを含む樹脂組成物で形成された樹脂層であり、透明樹脂層5は、バイオマス由来のオレフィンを5質量%以上含み、0.92g/cm3以上0.99g/cm3以下の範囲内の密度を有し、着色基材層2は、バイオマス由来のオレフィンを5質量%以上含み、0.92g/cm3以上1.12g/cm3以下の範囲内の密度を有し、絵柄層3は、着色剤とバイオマス由来成分とを含む。【選択図】図1
