This decorative sheet has a layer that includes at least a transparent resin film layer, the layer that includes at least the transparent resin film layer having on one surface thereof an asperity profile having recesses that reach the transparent resin film layer, and includes an area in which the depth (d) of the recesses of the asperity profile, and the thickness T from the start point of the depth (d) to the surface on the opposite side from the surface that has the asperity profile in the layer that includes the transparent resin film layer, satisfy the relationship (d)/T×100=5-10, and is intended for use as a decorative resin molded article in which a molding resin is laminated to the surface having the asperity profile.
