Abstract
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 (10) each equipped with a moth-eye structure (12). This transparent laminate (1) comprises a plurality of filmy members (10) which each comprise a base (11) and, disposed on at least one surface thereof, a structure (12) 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 (10) have been superposed, with a pressure-sensitive adhesive layer (2) interposed therebetween. In the superposed filmy members (10), there is a space (14) between the opposed structures (12).
