<p>Disclosed is a curable composition having good curability, adhesiveness and storage stability which uses a catalyst other than organic tin catalysts. Specifically disclosed is a curable composition composed of an organic polymer (A) having a reactive silicon-containing group and a silanol condensation catalyst (B) composed of at least one substance selected from organic tin compounds, carboxylic acids and amine compounds. This curable composition is characterized in that at least a part of the reactive silicon-containing group of the organic polymer (A) is a group represented by the following formula (1): -(CR<SUP>2</SUP> <SUB>2</SUB>)</p>
