The present invention is : a curable composition comprising a component (A) and a component (B) in a mass ratio (component (A):component (B)) of 100:0.1 to 100:50; a cured product obtained by curing the curable composition; and a method for using the curable composition as an optical device-securing adhesive or an optical device sealing material. The component (A) is a silane compound polymer that is represented by a formula (a-1)(where in the formula: R 1 is a group selected from an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, Z is a hydroxyl group, an alkoxy group having 1 to 10 carbon atoms, or a halogen atom, m is a positive integer, and n and o are independently 0 or a positive integer, provided that a plurality of R 1 are either identical or different, and a plurality of Z are either identical or different.), and the component (B) is a silane coupling agent that comprises a sulfur atom-containing functional group in its molecule.
