Abstract: A decorative sheet is provided that includes a paper substrate, a printed pattern layer arranged to face a major surface of the paper substrate, and a single-layer or multilayered surface protective layer arranged to face the pattern layer, the surface protective layer comprising a coating layer as an outermost layer of the decorative sheet, the coating layer being comprised of a coating containing antiviral additive particles (e.g., antiviral agent), the antiviral additive particles comprising finely divided silver. Further, the coating layer may contain a silicone-based component or a fluorine-based component, which imparts contamination resistance to the coating layer; the amount of the antiviral additive particles in the coating layer may be 0.2 mass % or more and 12 mass % or less relative to the total solid content of the coating layer; and the thickness of the coating layer may be 3 μm or more.
