PROBLEM TO BE SOLVED: To provide a curable composition for an optical material that simultaneously satisfies heat resistance, moisture resistance and transparency (low optical loss) in an optical communication wavelength and is excellent as a material for an optical waveguide in particular and to provide an optical waveguide having a member produced by curing the curable composition. SOLUTION: The curable composition for an optical material comprises, as the essential constituents, (A) a specific silicon-containing polymer, (B) a specific epoxy resin, and (C) an energy ray-sensitive cationic polymerization initiator.
