Abstract: A decorative sheet includes a primary film layer and a surface protection layer disposed on one surface of the primary film layer, wherein the surface protection layer includes on a surface thereof a ridged portion protruding in a shape of a ridge and thus has an uneven shape formed on the surface, the uneven shape of the surface protection layer has a ratio RSm/Ra in a range of 10 or more and 300 or less, the surface protection layer contains an ionizing radiation-curable resin as a main material, the ionizing radiation-curable resin contains as a main component an acrylic resin having a repeating structure, the acrylic resin has a dipentaerythritol structure, the repeating structure is one of structures of ethylene oxide, propylene oxide, and ε- caprolactone, and a number of repeating units of the repeating structure is 12 or more.

Abstract: There is provided a decorative sheet having excellent design properties, i.e., low gloss, and having fingerprint resistance, high durability (particularly scratch resistance or contamination resistance), and processability. A decorative sheet (1) according to this embodiment includes: a base material layer (2); and a surface protective layer (5) provided on one surface of the base material layer (2), in which the surface protective layer (5) has ridge-like parts provided to project in a ridge-like shape and form an irregular shape on the surface, RSm/Ra of the irregular shape of the surface protective layer (5) is within the range of 10 or more and 300 or less, the surface protective layer (5) contains an ionizing radiation curable resin as a main material, the ionizing radiation curable resin contains, as a main component, a tetrafunctional acrylic resin containing a repeating structure, the repeating structure is any one of the structures of ethylene oxide, propylene oxide, and ε-caprolactone, and the number of repetitions of the repeating structure is 12 or more.
