Abstract
A curable composition including: (A) an ester bond-containing organosilicon compound having two or more addition reactive carbon-carbon double bonds in one molecule, shown by the following general formula (1); (B) a silicon compound having two or more silicon atom-bonded hydrogen atoms in one molecule; and (C) a hydrosilylation reaction catalyst. This provides a curable composition to give a cured product with low gas permeability as well as excellent crack resistance and light transmission property.
