Disclosed is a curable silicone composition which has a gas barrier property and does not warp the substrate even when the substrate is sealed, and gives a transparent cured product having a hardness suitable for dicing. (A) (a) The following general formula (1): [Wherein R is a monovalent hydrocarbon group or alkoxy group which is unsubstituted or substituted by a halogen atom or the like] and a compound having two SiH bonds in one molecule, and (b) addition reactivity Addition reaction product of polycyclic hydrocarbon having two carbon-carbon double bonds in one molecule and addition reaction having two addition-reactive carbon-carbon double bonds in one molecule Reaction product, (B) a linear siloxane containing three or more SiH bonds and a phenyl group in one molecule, (C) a siloxane compound having an alkoxysilyl group and / or an epoxy group, and a SiH bond, And (D) a curable silicone-based composition comprising a hydrosilylation reaction catalyst.
