A transparent laminate including a transparent substrate and structure layer, wherein the structure layer contains protrusion portions, depression portions, or both on a surface thereof, and an average distance between the adjacent protrusion portions or between the adjacent depression portions is equal to or less than a visible light wavelength, the structure layer includes a polymerized product of an active energy ray curable resin composition, the resin composition includes a composition of a (meth)acryloyl group-containing polymerizable compound, the compound composition includes one or more from each of (A), (B), and (C):

Transparent laminate

The purpose of the present invention is to prevent an increase in reflectance and a decrease in transmittance, retain the intact instantaneousness and ease of stripping, improve the releasability of the adhesive, avoid the generation of distortion due to the thickness of the adhesive, and ensure the visibility, by laminating filmy members () each equipped with a moth-eye structure (). This transparent laminate () comprises a plurality of filmy members () which each comprise a base () and, disposed on at least one surface thereof, a structure () made up of recesses and protrusions which have been regularly arranged at a pitch not longer than the wavelengths of visible light. At least the ends of the filmy members () have been superposed, with a pressure-sensitive adhesive layer () interposed therebetween. In the superposed filmy members (), there is a space () between the opposed structures ().
