Abstract
A decorative sheet includes a substrate, a surface protective layer that covers the substrate, and raised portions situated between the substrate and the surface protective layer. The raised portions face first regions of the surface protective layer. The raised portions include a first binder resin, and first particles of which an average particle size is 10 μm or more. The surface protective layer includes a second binder resin, and second particles of which an average particle size is 10 μm or more and 20 μm or less. An average thickness of the raised portions is 20 μm or more. An average thickness of the surface protective layer is 3 μm or more and 15 μm or less.
