1. A curable composition comprising:
(A) silica fine particles surface-modified with silane compounds that comprise (A1) a polymerizable silane compound represented by the following general formula (1) and (A2) a silane compound different from the polymerizable silane compound (A1), (B) (meth)acrylate compounds comprising (B1) a (meth)acrylate compound having at least one (meth)acryloyloxy group and having no cyclic structures and (B2) a (meth)acrylate compound having at least one(meth)acryloyloxy group and having an alicylic structure, and (C) a polymerization initiator,
SiR1aR2bR3c(OR4)4-a-b-c  (1) wherein R1 is a hydrocarbon group having 11 to 20 carbon atoms that has an ethylenic unsaturated group, or a substituted hydrocarbon group having 11 to 20 carbon atoms that has an ethylenic unsaturated group and has an ether bond and/or an ester bond; R2 is a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; R3 is a halogen atom; R4 is a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; a is an integer of 1 to 3; b is an integer of 0 to 2; c is an integer of 0 to 3; the sum of a and b is 1 to 3; the sum of a, b and c is 1 to 4; when a is 2 or more, multiple R1 may be the same or different from each other; when b is 2, multiple R2 may be the same or different from each other; when c is 2 or more, multiple R3 may be the same or different from each other; and when the sum of a, b and c is 1 or 2, multiple R4 may be the same or different from each other.
