The present invention is a curable composition containing the following components (A) to (C), a method for producing the same, a cured product obtained by curing the curable composition, and the curable composition as an optical element fixing material A method for using an adhesive or a sealing material for an optical element fixing material, and an optical device, wherein the curable composition is characterized in that the mass ratio of the (A) component and the (B) component is [(A) Component:(B) component]=100:0.3～100:50 ratio contains (A) component and (B) component. (A) Component: a curable polysilsesquioxane compound having a repeating unit represented by the formula (a-1): R 1 SiO 3/2 , in which R 1 represents a substituted or unsubstituted An alkyl group having 1 to 10 carbon atoms or a substituted or unsubstituted aryl group. (B) Component: fine particles having an average primary particle diameter of 5 to 40 nm. (C) component: the silane coupling agent which has a nitrogen atom in a molecule|numerator. ADVANTAGE OF THE INVENTION According to the present invention, it is possible to provide a curable composition which can provide a cured product having good adhesion, peeling resistance, and heat resistance, and which has good workability in the coating process, a method for producing the same, and curing of the curable composition. The resulting cured product, a method of using the curable composition as an adhesive for an optical element fixing material or a sealing material for an optical element fixing material, and an optical device. |
