Abstract

The present invention relates to a curable silicone composition comprising: (A) an organopolysiloxane represented by a specific average unit formula, (B) an optional straight-chain organopolysiloxane having at least two alkenyl groups and not having any silicon-bonded hydrogen atoms in a molecule, (C) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule, and (D) a hydrosilylation reaction catalyst. The curable silicone composition has high reactivity and forms a cured product with low gas permeability.
