    • A curable silicone composition comprising: an alkenyl-containing organopolysiloxane (A) that contains: a dialkylpolysiloxane (A-1) having on average at least 2 alkenyl groups in one molecule having a 25°C viscosity in the range of 5,000 to 35,000 mPa.s, and a alkenyl-containing organopolysiloxane resin (A-2) consisting of SiOunits, RRSiOunits, and RSiOunits (where Rdesignates alkyl groups with 1 to 10 carbon atoms, and Rdesignates alkenyl groups) with the content of alkenyl groups ranging from 3.5 to 5.0 mass %, and with the ratio of the sum of the mole numbers of the RRSiOunits and RSiOunits to 1 mole of the SiOunits in the range from 0.5 to 1.4; an organopolysiloxane (B), wherein silicon-bonded hydrogen atoms are in an amount of at least 0.7 mass %; and a hydrosilylation catalyst (C). The composition is capable of forming a flex-resistant highly transparent cured silicone product with non-tacky surface.
