A decorative sheet that has good scratch resistance and provides a soft and supple feel is provided. In the decorative sheet, a surface of the surface protective layer is provided with asperities including ridge portions. In a power spectrum image obtained by applying a two-dimensional fast Fourier transform to their surface shape image, when the average luminance in the spatial frequency range of: i) 95-105 cycles/mm is P_100, ii) 195-205 cycles/mm is P_200, iii) 695-705 cycles/mm is P_700, and the ratio of the difference between P_100 and P_700 to the difference between P_200 and P_700 is Rt_P, the average of Rt_P is within the range of 1.57-1.82. The surface protective layer contains 100 parts by mass of a cured resin and 3-11 parts by mass of particles with an average particle size of 3 μm or more, and has a thickness of 2-18 μm and a gloss <10.
