Decorative sheet and method for producing decorative sheet

A decorative sheet, comprising:

• 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 has one of ethylene oxide, propylene oxide, and ε-caprolactone structures,
• a number of repetitions of the repeating structure is 12 or more,
• the surface protection layer has a thickness of 2 μm or more and 25 μm or less,
• the surface protection layer includes particles having an average particle size of 10 μm or less,
• an addition amount of the particles is in a range of 0.5 parts by mass or more and 10 parts by mass or less, relative to 100 parts by mass of the ionizing radiation-curable resin;
• and
• the ionizing radiation-curable resin is selected from the group consisting of ethoxylated dipentaerythritol pentaacrylate, ethoxylated dipentaerythritol hexaacrylate, propoxylated dipentaerythritol hexaacrylate and caprolactone-modified dipentaerythritol hexaacrylate.
