ABSTRACT:
An antireflective film, comprising a film composed of an inorganic chemical compound consisting of Mg, Si, O and F and a film composed of an inorganic chemical compound consisting of Zr, Si and O. The film shows antireflective property over a wide spectral range even with a limited number of layers. An optical element comprising a transparent body is provided with, a film formed thereon, composed of an inorganic chemical compound consisting of Zr, Si and O and a film formed as an outermost layer facing the air, composed of an inorganic chemical compound consisting of Mg, Si, O and F.
