PROBLEM TO BE SOLVED: To provide a curable composition having improved compatibility and cast moldability. SOLUTION: The curable composition contains (A) an organic compound having at least two carbon-carbon double bonds reactive with SiH group in one molecule, (B) a compound having at least two SiH group in one molecule and (C) a hydrosilylation catalyst as essential component. The component B contains a compound (B1) obtained by the hydrosilylation reaction of (α1') an organic compound having at least two carbon-carbon double bonds reactive with SiH group in one molecule and (α2') an organic compound containing one carbon-carbon double bond reactive with SiH group in one molecule with (β1') a cyclic polyorganosiloxane having 3 or more SiH groups in one molecule.
