<p>The present invention relates to: a curable composition comprising the following components (A) and (B) at a mass ratio between said component (A) and said component (B) (component (A):component (B)) of from 100:0.3 to 100:8; a cured product made by curing said composition; and a method for using said composition as an adhesive for optical elements or a sealing agent for optical elements. Component (A): a silane compound copolymer represented by formula (a-1) (wherein R1 represents a hydrogen atom, etc.; X0 represents a halogen atom, a cyano group, or a group represented by formula OG (wherein G represents a protecting group of a hydroxyl group); D represents a single bond, etc.; R2 represents a C1-20 alkyl group that is not substituted or that includes a substituent (except for halogen atoms, cyano groups, and the group represented by the formula OG), etc.; Z represents a hydroxyl group, etc.; m and n each independently represent a positive integer; o, p, q, and r each independently represent 0 or a positive integer). Component (B): a silane coupling agent including a sulfur-atom-containing functional group in the molecule thereof.</p> |
