Abstract: Provided is a molded structure that demonstrates hydrophilicity with only a fine relief structure on the surface of a resin substrate, has anti-fogging and self-cleaning functions over a long period of time, and maintains transparency in the case the resin substrate is transparent. The molded structure comprises the formation of a fine relief structure on one surface of a resin substrate (1) that continuously prevents a water aggregation phenomenon and demonstrates hydrophilicity for forming a water film, wherein the width or diameter of protrusions (2) of the fine relief structure is equal to or less than the shortest wavelength of visible light, and the center-to-center distance between the protrusions (2) is 200 nm to 400 nm.
