PROBLEM TO BE SOLVED: To provide a method for manufacturing a decorative sheet which maintains surface smoothness, gloss and attractive feeling in either of a high-gloss decorative sheet and a low-gloss decorative sheet even after three-dimensional molding such as insert molding or injection molding with decoration. SOLUTION: The method for manufacturing a decorative sheet includes a process for forming a design layer on a base material, a process for smoothing a surface of the design layer, a process for laminating an ionizing-radiation-curable resin composition on the smooth surface of the design layer, and a process for forming a surface protecting layer by curing the ionizing-radiation-curable resin composition. Furthermore, the method includes a process for roughening the surface so that ten-point average roughness RzJIS of the rear surface of the decorative sheet and thickness T of the base material satisfy T×0.30>RzJIS (I), and arithmetic average roughness Ra and thickness T of the base material satisfy T×0.20>Ra≥T×0.005 (II).
