Abstract
The present invention relates to a curable silicone composition comprising: (A) an alkenyl group-containing organopolysiloxane having a condensed polycyclic aromatic group or a group containing a condensed polycyclic aromatic group; (B) an organopolysiloxane resin having at least two alkenyl groups in a molecule; (C) an organosiloxane (C1) having silicon-bonded hydrogen atoms at both molecular terminals, an organopolysiloxane (C2) having at least two silicon-bonded hydrogen atoms in a molecule, or a mixture of components (C1) and (C2); and (D) a hydrosilylation reaction catalyst. The curable silicone composition has excellent handleability and can form a cured product with a high refractive index and low gas permeability.
