摘要：<p>An organopolysiloxane which forms a cured product having a high refractive index, high transparency, and excellent heat resistance when subjected to a hydrosilylation reaction and which is represented by the following average unit formula: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(R 1 3 SiO 1/2 ) a (R 1 2 SiO 2/2 ) b (R 2 SiO 3/2 ) c (SiO 4/2 ) d wherein, R 1 are alkyl groups, alkenyl groups, phenyl groups, or hydrogen atoms; R 2 is a group represented by R 1 or a condensed polycyclic aromatic group or a group containing a condensed polycyclic aromatic group, but at least one of R 1 or R 2 in a molecule is an alkenyl group or a hydrogen atom, at least one R 2 in a molecule is a condensed polycyclic aromatic group or a group containing a condensed polycyclic aromatic group; and a, b, c and d are numbers that satisfy: 0.01 ‰¤ a ‰¤ 0.8, 0 ‰¤ b ‰¤ 0.5, 0.2 ‰¤ c ‰¤ 0.9, 0 ‰¤ d < 0.2 and a + b + c + d = 1.</p>
