Abstract: An anti-fog sheet structure includes: a substrate made of polycarbonate, a first synthetic polymer film formed on a first main surface side of the substrate, and a second synthetic polymer film formed on a second main surface side, wherein the first synthetic polymer film has, on its surface, a plurality of first bumps having an equivalent circular area diameter Dp1 in the range of more than 50 nm and less than 500 nm, the second synthetic polymer film has, on its surface, a plurality of second bumps having an equivalent circular area diameter Dp2 in the range of more than 20 nm and less than 500 nm, and the first synthetic polymer film is formed from a cured product of a photocurable resin containing 30 mass % or more of ethoxylated pentaerythritol tetraacrylate.
