A photocurable silicone composition easy to manufacture, free of variations in adhesion and effective as a potting material or the like is provided. The composition is prepared by adding a silanol terminated organosiloxane to an amino group-containing organodialkoxysilane, then reacting the resulting amino group-containing organopolysiloxane with a vinyl group-containing isocyanate, acrylic anhydride, methacrylic anhydride, acrylic halide or methacrylic halide and combining the resulting photocurable organopolysiloxane with a photopolymerization catalyst.
