The curable polyfluorene oxide composition of the present invention has excellent adhesion to an optical semiconductor element, a lead frame, a substrate, a bonding wire, and the like in an optical semiconductor device, and includes at least: (A) an organopolyoxane, which is one a molecule having at least two alkenyl groups bonded to a ruthenium atom; (B) an organohydrogenated polyoxyalkylene having at least two hydrogen atoms bonded to a ruthenium atom in one molecule; (C) a triazole compound (D) a metal-based condensation reaction catalyst; and (E) a catalyst for hydrogenation reaction. Further, in the optical semiconductor device of the present invention, the optical semiconductor element is sealed or coated with the cured product of the composition, and the reliability after the moisture absorption reflow test is excellent. |
