Abstract To provide a decorative sheet excellent in scratch resistance while capable of preventing an elongation at print processing and of reducing occurrence of flexural whitening or a crack, and a manufacturing method of the decorative sheet.SOLUTION: A decorative sheet 1 includes a substrate layer 2 composed of a pigmented polypropylene film formed by mixing an inorganic pigment in a polypropylene resin. Furthermore, the substrate layer 2 contains a nano-sized nucleating agent. Furthermore, the substrate layer 2 has a value 0.7-0.9 of peak intensity ratio x calculated from an absorption spectrum obtained at Fourier-type infrared spectroscopy. Furthermore, the substrate layer 2 is 50-150 μm thick.SELECTED DRAWING: Figure 1 【課題】本発明は、印刷加工時の伸びを抑制し、曲げ白化や割れの発生を低減することが可能であり、且つ耐傷性に優れた化粧シート及びその化粧シートの製造方法を提供することを目的とする。【解決手段】本実施形態の化粧シート1は、無機顔料をポリプロピレン樹脂に混合して形成された着色ポリプロピレンフィルムからなる基材層2を有する。また、基材層2はナノサイズの造核剤を含有している。また、基材層2は、フーリエ型赤外分光測定において得られた吸光スペクトルから算出されるピーク強度比xの値が、0.7以上0.9以下である。また、基材層2の厚さは、50μm以上150μm以下である。【選択図】図1
