Abstract
The invention provides an optical element that has a low refractive-index chromatic dispersion, a high degree of freedom in molding or forming as is the case with synthetic resins, and moldability or formability that lends itself to mass production. The optical element is obtained by molding or otherwise forming a composition containing a first material that is a fine particle having an Abbe number vd of 80 or greater indicative of a chromatic dispersion in a visible range and having a size of less than 400 nm, and a second material that is an organic/inorganic hybrid material comprising an organic polymer material having a carbon-carbon bond in a main chain and an inorganic component.
