ABSTRACT:
An optical element is disclosed which is resistant to changes in environmental characteristics such as temperature and humidity and achieves a stable and favorable reflection suppressing effect. The optical element has a base member and a resin layer which is formed on the base member and has a linear expansion coefficient different from that of the base member. The resin layer has a minute periodic structure which has a period smaller than the wavelength of incident light on the optical element.
