Abstract
An optical element is formed from a molded body which is formed using an impact consolidation phenomenon in which mechanical impact is applied to ultra fine fragile particles which are supplied onto a substrate so that the ultra fine fragile particles are pulverized and bonded to each other. In the optical element, d6/λ4<4×10−5 nm2 holds, in which d (nm) represents the average radius of a part of the molded body, such as a pore (void) or a different phase, having a refractive index different from that of a primary component of the molded body, and in which λ (nm) represents the wavelength of light transmitting through the molded body.
