Abstract
A curable silicone composition is disclosed. The curable silicone composition comprises: (A) a linear organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule; (B) a branched organopolysiloxane represented by the average unit formula; (C) an organosiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule; and (D) a hydrosilylation reaction catalyst. The curable silicone composition forms a cured product having good mechanical properties and good retention of transparency under conditions of high temperature.
