PROBLEM TO BE SOLVED: To obtain a highly dielectric, addition-curable composition which is in a liquid state and is therefore easily handled without any solvent, shows a low moisture-absorption, exerts an excellent film-forming property and forms a cured product exerting excellent dielectric properties with a large dielectric constant and a small dielectric loss. SOLUTION: This composition contains (a) an organopolysiloxane containing a cyanoalkyl group and a monovalent hydrocarbon group having an aliphatic unsaturated bond, (b) a cyanoalkyl group-containing organohydrogenpolysiloxane and (c) a platinum group metal-based catalyst.
