Abstract
A decorative sheet includes a design layer, a primer layer and a surface protective layer formed by cross-linking and curing an ionizing radiation curable resin composition in this order on a base material. A surface of the surface protective layer is smooth. In one aspect, a ten point average roughness RzJIS on a rear face of the decorative sheet and a thickness T of the base material satisfies the following equation (I); and an arithmetic average roughness Ra on the rear face and a thickness T of the base material satisfies the following equation (II): T×0.30≧RzJIS (I) T×0.20≧Ra≧T×0.005 (II). In another aspect, an arithmetic average roughness Ra on a rear face of the decorative sheet is 1.0 to 10.0 μm.
