Abstract
To offer curable silicone compositions with outstandingly high thixotropy, which can form hardened material with an outstanding refractive index transparency. The problem above is solved by curable silicone compositions which include (A) alkenyl group-containing organopolysiloxane which has at least two silicon-bonded alkenyl groups per molecule, (B) organo-hydrogen polysiloxane which has at least two silicon-bonded hydrogen atoms per molecule, (C) silica-titania composite oxide particles at ≥3 mass % of the total mass of the composition, and (D) a curing catalyst.
