Abstract
A problem of the present invention is to provide a curable composition which gives good curability, adhesiveness and storage stability by use of a catalyst other than organic tin catalysts. The above problem is solved by a curable composition, comprising: (A) one or more organic polymers having a reactive-silicon-containing group, and (B) a silanol condensation catalyst consisting of one or more compound(s) selected from organic tin compounds, carboxylic acids, and amine compounds, wherein at least one part of the reactive-silicon-containing group(s) of the organic polymer(s) (A) is represented by the following general formula (1): —(CR)—(SiRXO)—SiX(1), and the silanol condensation catalyst (B) consists of amine compound(s) (B1) or consists of amine compound(s) (B1) and a carboxylic acid (B2), and when the mol number of the amine compound(s) is regarded as 1, the ratio by mol of the total amount of the carboxylic acid(s) to the amount of the amine compound(s) is 0.1 or less.
