Abstract
A composite material () includes a resin (), and first inorganic particles () dispersed in the resin and containing at least zirconium oxide. The composite material has a refractive index at the d line nof not less than 1.60 and an Abbe's number νof not less than 20, and satisfies a relationship n≧1.8−0.005 ν. This composite material exhibits both a high refractive index and low dispersion in good balance, and has excellent workability. Accordingly, using this composite material makes it possible to realize a small optical component having favorable wavelength characteristics.
