An optical element is provided which reflects a reduced amount of light even under a very high intensity lighting system used for a surgical operation, a dental treatment etc., has anti-fogging performance, and is transparent and useful for face protection. The optical element 1 has a flexible transparent substrate (a substrate 11) and a plurality of structures 12 disposed on opposite surfaces of the substrate at a pitch equal to or less than the wavelength of visible light. The structures 12 are formed from a cured product of a resin having a hydrophilic functional group. |
