The present invention is: a curable composition containing component (A) and component (B) at a ratio of 100:0.1 to 100:70 (component (A): component (B)) in terms of the mass ratio of component (A) and component (B); a cured product obtained by curing the aforementioned composition; and a method for using said composition as an adhesive agent for an optical element. Component (A) is a silane compound copolymer represented by formula (a-1) [In the formula, R1 represents a hydrogen atom; X0 represents a sulfur atom-containing functional group; D represents a C1-20 bivalent hydrocarbon group having a single bond, or an unsubstituted or substituted group; R2 represents a C1-20 alkyl group having an unsubstituted or substituted group (excluding a sulfur atom-containing functional group), or a phenyl group having an unsubstituted or substituted group; Z1 and Z2 represent a hydroxyl group or a C1-10 alkoxy group; m represents a positive integer; and n, o, p, q, and r represent a 0 or a positive integer. The ratio between (m+o+q) and (n+p+r) is 0.3:99.7 to 80:20 when (m+o+q):(n+p+r).]. Component (B) is a silane coupling agent having a nitrogen atom within a molecule. |
