Abstract: A UV-curable silicone composition includes (A) an organopolysiloxane containing at least two alkenyl groups bonded to silicon; (B) a linear organohydrogenpolysiloxane having at least one Si—H bond in a side chain and having three of more Si—H bonds in total; (C) a siloxane compound having at least two Si—H bonds and having one hydrolyzable group bonded to a siloxane skeleton via a heteroatom-containing structure; and (D) a platinum catalyst, the UV-curable silicone composition being such that the total of the Si—H bonds contained in the components (B) and (C) is 0.1 to 2.0 equivalents relative to 1 equivalent of the alkenyl groups in the component (A), and the ratio of the number of Si—H bonds derived from the component (C) to the number of Si—H bonds in the whole of the composition is 0.2 or more.
