An object of the present invention is to provide, for use in living environments, a decorative sheet that has excellent, easy cleanability and excellent impact resistance and from which dirt due to the adherence of a daily used contaminant, such as fine particle powder, that is not easy to clean is easily removed. The present invention provides a decorative sheet having a surface-protecting layer on the uppermost surface thereof, wherein (1) Ra(i)/Ra(ii) is 0.62 or more and 1.63 or less, the Ra(i)/Ra(ii) being calculated using an arithmetic average roughness Ra(i) measured along an arbitrary direction on the surface of the surface-protecting layer, and an arithmetic average roughness Ra(ii) measured along the perpendicular direction to the arbitrary direction, under measurement conditions in accordance with JIS B0633:2001 and by a measurement method in accordance with JIS B0601:2001; (2) RSm(i)/RSm(ii) is 0.75 or more and 1.33 or less, the RSm(i)/RSm(ii) being calculated using a mean width of roughness profile elements RSm(i) measured along an arbitrary direction on the surface of the surface-protecting layer, and a mean width of roughness profile elements RSm(ii) measured along the perpendicular direction to the arbitrary direction, under measurement conditions in accordance with JIS B0633:2001 and by a measurement method in accordance with JIS B0601:2001; and (3) an arithmetic average roughness Ra measured on the surface of the surface-protecting layer at a cutoff value (»c) of 0.08 mm with an evaluation length of 0.4 mm by a measurement method in accordance with JIS B0601:2001 is 0.40 µm or less, and a mean width of roughness profile elements RSm measured on the surface of the surface-protecting layer at a cutoff value (»c) of 0.08 mm with an evaluation length of 0.4 mm by a measurement method in accordance with JIS B0601:2001 is 22.90 µm or more.
