PROBLEM TO BE SOLVED: To provide a curable composition having photocurability and giving a cured product excellent in heat resistant transparency.SOLUTION: As essential components, the curable composition comprises: (A) a compound having an alkenyl group and a photopolymerizable functional group in the same molecule; (B) a compound having an SiH group; (C) a photopolymerization initiator; and (D) a hydrosilylation catalyst. Since two kinds of reactions, which are a photopolymerization reaction between a photopolymerizable functional group of the component (A) and the component (C) and a hydrosilylation reaction between an alkenyl group of the component (A) and the components (B) and (D), proceed, insulating properties better than that of a general-purpose photocurable resin can be exhibited while maintaining photocurability. |
