Abstract: A decorative sheet includes: a primary film layer; and a surface protective layer, wherein the surface protective layer has a gloss level of 15 or less, the surface protective layer includes a ridged portion projecting in a ridged pattern from a surface of the surface protective layer to form an uneven shape on the surface, the surface protective layer contains an ionizing radiation-curable resin as a main material, the ionizing radiation-curable resin contains, as a main component, a tetrafunctional acrylic resin having a repeating structure, the number of repetitions of the repeating structure is 12 or more, a content of vinyl groups contained in the ionizing radiation-curable resin is 20% or less relative to carbonyl groups contained in the ionizing radiation-curable resin, and the uneven shape of the surface protective layer (5) has RSm/Ra in a range of 10 or greater and 300 or less.
