It is an object of the present invention to provide a curable composition retaining curability even at a low temperature of -20 to 5° C. and having a low viscosity at such low temperature, the cured product of which is an artifact having excellent water resistance, chemical resistance, mechanical strength and other physical properties. The present invention is directed to a curable composition which comprises a hetero ring-containing compound (A) of the following general formula (1), a compound (B) having 2 or more electrophilic groups reactive with thiol or -S- groups per molecule, and a compound (C) having 2 or more nucleophilic groups per molecule:wherein n represents an integer of 1 to 10; X1, Y1 and Z1 each represents an oxygen or sulfur atom; R1 represents the residue of a cyclic ether group-containing compound (D) or a hydrogen atom; R2 represents a hydrocarbon group of 2 to 10 carbon atoms.
