The present invention has its object to provide a curable composition which comprises an amidine compound as a non-organotin catalyst and shows good elongation, flexibility, surface curability, depth curability and adhesiveness; the above object can be achieved by a non-organotin curable composition which comprises: (A) an organic polymer containing a silyl group capable of crosslinking under siloxane bond formation, the silyl group being a group represented by the general formula (1): -SiR1X2; (B) an amidine compound (B-1) as a silanol condensation catalyst; and (C) a carboxylic acid, wherein the ratio between the number of moles (b) of all nitrogen atoms in the (B-1) component of the composition and the number of moles (c) of all carboxyl groups in the (C) component of the composition, namely the ratio (b)/(c), is higher than 2.
