[Problem] The purpose of the present invention is to provide a curable composition in which at least one property from among transparency and heat resistance of a formed cured material, storage stability of the composition, and handling properties and moldability is enhanced relative to the conventional curable composition. [Solution] A curable composition containing: silica microparticles (A), surface-modified by one or more silane compounds including at least a polymerizable silane compound (A1) represented by general formula (1); a (meth)acrylate compound (B); and a polymerization initiator (C). [In formula (1), R 1 represents a C 11 -C 20 hydrocarbon group having an ethylenically unsaturated group, or a C 11 -C 20 substituted hydrocarbon group having an ethylenically unsaturated group and an ether bond and/or ester bond, R 2 represents a hydrogen atom or a C 1 -C 4 hydrocarbon group, R 3 represents a halogen atom, and R 4 represents a hydrogen atom or a C 1 -C 10 hydrocarbon group; a represents an integer of 1-3; b represents an integer of 0-2; c represents an integer of 0-3; the sum of a and b is 1-3; and the sum of a, b, and c is 1-4.] |
