ABSTRACT:
A composite material (10) includes a resin (12), and first inorganic particles (11) dispersed in the resin and containing at least zirconium oxide. The composite material has a refractive index at the d line nCOMdof not less than 1.60 and an Abbe's number νCOMof not less than 20, and satisfies a relationship nCOMd≧1.8−0.005 νCOM. 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.
