PROBLEM TO BE SOLVED: To provide a curable organopolysiloxane composition which forms a cured material having a high refractive index, high light transmittance, and good adhesion to a substrate, and to provide a semiconductor device having excellent reliability.SOLUTION: Provided is a curable organopolysiloxane composition comprising: (A) an organopolysiloxane represented by an average composition formula having alkenyl groups and aryl groups; (B) an organopolysiloxane having at least two hydrogen atoms bound to silicon atoms in one molecule, and in which 15 mole% or more of total organic groups bound to silicon atoms is aryl groups; (C) a branched organopolysiloxane represented by an average composition formula having alkenyl groups, aryl groups, and epoxy-containing organic groups; and (D) a catalyst for a hydrosilylation reaction, and to provide a semiconductor device made by coating a semiconductor element by a cured material of the composition. |
