Abstract: A UV-curable silicone composition includes a polyorganosiloxane (A) containing at least two silicon-bonded alkenyl groups in the molecule; a polyorganohydrogensiloxane (B) having a branched or three-dimensional network structure and containing at least three silicon-bonded hydrogen atoms in the molecule; a polyorganohydrogensiloxane (C) having a linear or cyclic structure and containing two silicon-bonded hydrogen atoms in the molecule; and a UV-active addition reaction curing catalyst (D). The component (B) includes a polyorganohydrogensiloxane (E) having a branched or three-dimensional network structure and containing at least one silicon-bonded alkoxy group SiOR0 (R0 is a C1-C5 alkyl group) and at least three silicon-bonded hydrogen atoms in the molecule.
