<P>PROBLEM TO BE SOLVED: To provide a curable silicone composition which provides a cured product having large resistance against a stress such as thermal shock, having excellent property of extracting light from a light source because of a high refractive index thereof, and having excellent heat resistance and therefore, is useful as a material for optical devices/optical parts such as an LED element sealing material, an insulating material for electronic devices/electronic parts, or a coating material; and a cured product thereof. <P>SOLUTION: This curable silicone composition includes (A) a specific diphenylsiloxane-based compound having at a molecular chain terminal thereof, an alkenyl group bonded to a silicon atom, (B) an organic silicon compound having at least two hydrogen atoms bonded to a silicon atom, and (C) a catalyst for a hydrosilylation reaction, and provided is also a cured product prepared by curing the composition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
