PROBLEM TO BE SOLVED: To provide a curable composition that exhibits excellent durability after cured. SOLUTION: The curable composition comprises a polymer, containing an alkylene oxide monomer unit in its main chain and containing at least one hydrolyzable silicon-containing group per one molecule, and silanol group-containing silica, where the content of silica is such an amount that the surface area of the silica is at least 10 m<SP>2</SP>relative to 1 g of the polymer.
