PROBLEM TO BE SOLVED: To obtain the subject composition having curability, especially capable of shortening a time required to attain the development of adhesiveness by including an organic polymer containing a specific reactive end group and an epoxy resin as essential components. SOLUTION: This composition comprises (A) a polymer containing a hydrolyzable silicon group of the formula (R1 is a 1-20C monofunctional organic group; X is a hydroxyl group or a hydrolyzable group; (a) is 1, 2 or 3) in which the polymer is partially or wholly a polymer containing a group in which (a) is 3 in the formula and (B) an epoxy resin as essential components. The component A has preferably 8,000-50,000 molecular weight. The component A is preferably a polyoxyalkylene polymer having a molecular weight distribution Mw/Mn of <=1.7, containing the hydrolyzable silicon group of the formula. The ratio of the component B used is in the ratio of A/B of preferably 100/1 to 100/300 by weight. Consequently excellent adhesiveness to various substrates can be exhibited in a short time.
