PROBLEM TO BE SOLVED: To provide a photocurable composition enabling a lightweight polymer material having good moldability and a high dielectric constant to be formed, and a cured product comprising the photocurable composition.SOLUTION: There is provided the photocurable composition comprising as essential components, (a) silsesquioxane having a cyano group represented by formula (1), (b) an ethylenically unsaturated monofunctional monomer having a cyano group, (c) an ethylenically unsaturated polyfunctional monomer and (d) a photoinitiator. In the formula (1), A and B represent each independently a bivalent hydrocarbon group having 1 to 10 carbon atoms, R and Rrepresent each independently a monovalent hydrocarbon group having 1 to 6 carbon atoms, G is an alkyl group having 1 to 8 carbon atoms or the like and one or two hydrogen atom is substituted by a monovalent substituent such as a carboxyl group or an ester group having 2 to 4 carbon atoms, m, n, p, q, r and s represent each independently an integer of 0 to 200, sum of m+q is 4 or more, sum of m+n+p is 4 to 200 and total sum of m+n+p+q+r+s is 4 to 200.SELECTED DRAWING: None |
