To provide a decorative sheet with little change in design before and after stretching.SOLUTION: There is provided a decorative sheet comprising a resin base layer, a colored layer, and a transparent resin layer in this order in a thickness direction, wherein an absolute value of a difference between L* in an SCE system measured from the transparent resin layer side after subjecting the decorative sheet to a tensile test (room temperature, stretch ratio 40%), and L* in the SCE system measured from the transparent resin layer side before subjecting the decorative sheet to the tensile test, is 1.5 or less, in an L*a*b* color system.SELECTED DRAWING: Figure 1
【課題】延伸前後において意匠性の変化が小さい加飾シートを提供する。【解決手段】樹脂基材層と、着色層と、透明樹脂層とを厚さ方向にこの順に備える加飾シートであって、L*a*b*表色系において、加飾シートを引張試験(室温、延伸率40%)に供した後に透明樹脂層側から測定されたSCE方式でのL*と、加飾シートを引張試験に供する前に透明樹脂層側から測定されたSCE方式でのL*との差の絶対値が、1.5以下である、加飾シート。【選択図】図1
