The present invention relates to: a curable composition which contains the components (A)-(E) described below so that the mass ratio of the component (A) to the component (B), namely (A):(B) is from 100:0.3 to 100:20; a cured product; a method for using a curable composition; and an optical device. (A) a silane compound polymer represented by formula (a) (wherein R1 represents an alkyl group having 1-10 carbon atoms; Z represents a hydroxyl group or the like; s represents a positive integer; and each of t and u represents 0 or a positive integer) (B) fine particles having an average primary particle diameter of more than 0.04 μm but 8 μm or less (C) a silane coupling agent having a nitrogen atom (D) a silane coupling agent having an acid anhydride structure (E) a silane coupling agent having a sulfur atom-containing functional group The present invention provides: a curable composition which enables the achievement of a cured product that has excellent releasability and excellent heat resistance, while having high adhesive force; a cured product which is obtained by curing the composition; a method for using the composition as an adhesive for optical elements, and the like; and an optical device.
