PROBLEM TO BE SOLVED: To obtain a curable composition with good storage stability, good physical characteristics such as tensile physical properties of a rubber after curing and good water-resistant adhesiveness in the curable composition comprising an isocyanate group-containing urethane prepolymer. SOLUTION: This curable composition comprises (A) the isocyanate group-containing urethane prepolymer, (B) a silicate capable of regenerating a polyol by hydrolysis with moisture, and if necessary, (C) a metal chelating compound. In the curable composition, as (B) the silicate, a silicate in which a hydrocarbon group with≥7C which may have a substituent and may contain an oxygen atom or a nitrogen atom in the chain is bonded to a silicon atom, is used. The curable composition has good storage stability, and good physical characteristics such as tensile physical properties of the rubber after curing and good water-resistant adhesiveness.
