Abstract
The present invention is a curable organopolysiloxane composition containing (A) a compound shown by the following average composition formula (1), wherein Rrepresents an aliphatic unsaturated group, Rrepresents a monovalent hydrocarbon group, Rrepresents an aliphatic hydrocarbon group, Ar represents an aryl group, and 'n' and 'm' represent positive numbers which satisfy n≧1, m≧1, and n+m≧10, (B) a hydrogen atom-containing organic silicon compound having at least two silicon atom-bonded hydrogen atoms per one molecule while not having an aliphatic unsaturated group, and (C) a hydrosilylation catalyst which contains a platinum group metal. Thereby, there can be provided a curable organopolysiloxane composition which can give a cured product having high transparency, high refractive index, and excellent thermal shock resistance; an optical device sealing material; and an optical device.
