Abstract
Provided is a silicon-containing curable composition which includes a prepolymer (A) containing two or more Si—H groups in one molecule, which is obtained by subjecting one or more kinds of a cyclic siloxane compound (α) represented the following formula (1) and one or more kinds of a compound (β) represented by the following formula (2), to a hydrosilylation reaction; a cyclic siloxane compound (B) containing, in one molecule, two or more carbon-carbon double bonds that are reactive with Si—H groups; a polysiloxane compound (C) which is different from the prepolymer (A) and the cyclic siloxane compound (B); and a hydrosilylation catalyst (D). In formula (1), R1 to R3 each represent an alkyl group having 1 to 6 carbon atoms, or a phenyl group; a represents a number from 2 to 10; and b represents a number from 0 to 8. In formula (2), n represents the number 1 or 2.
