Abstract: A decorative sheet includes at least a topcoat layer disposed to face a substrate layer in a first direction, the front surface of the topcoat layer having a wavy roughness profile measured with a cutoff wavelength λs of 8 μm and a cutoff wavelength λc of 2.5 mm according to JIS B0601:2001 in a second direction perpendicular to the first direction, a selected evaluation portion of the wavy roughness profile comprising a plurality of profile elements, an evaluation length of the selected evaluation portion of the wavy roughness profile having 10 mm, the selected evaluation portion of the wavy roughness profile being designed to have an arithmetic mean deviation Ra of 10 μm or less; and to have a mean width of the profile elements and a ten point height, the mean width and the ten point height satisfying the following expression: 5≤RSm/RzJIS≤40 . . . (1), where RSm represents the mean width, and RzJIS represents the ten point height.
