Provided is a curable composition which is free of organotin compounds to be environmentally friendly and whose cured product shows high elongation and high elastic recovery to be suitable particularly as a sealant. The present invention relates to a curable composition containing a reactive silyl group-containing organic polymer (A) which has a highly active reactive silyl group at a molecular chain end, and a compound (B) having 2 to 10 ethyloxy groups in its molecule but having no amino group in its molecule, the compound (B) being a C1-C20 saturated hydrocarbon having one alkoxysilyl group, a C1-C20 hydrocarbon having two or more alkoxysilyl groups, or a C1-C20 polycarboxylic acid ester.
