The present invention provides a curable composition that has a high degree of hardness, excellent heat resistance and crack resistance, and is useful as a sealing material for optical elements and the like. The curable composition according to the present invention is a polycyclic hydrocarbon group-containing silicone-based curable composition comprising:
(A) an addition reaction product of (a) a specific organosilicon compound containing two hydrosilyl groups, and (b) a polycyclic hydrocarbon containing two addition reactive carbon-carbon double bonds within each molecule, wherein the addition reaction product contains at least two addition reactive carbon-carbon double bonds within each molecule,
(B) a compound containing three or more hydrogen atoms bonded to silicon atoms within each molecule,
(C) a hydrosilylation reaction catalyst, and
(D) a stabilizer containing a hindered amine structure and a phenol structure within each molecule. |
