PROBLEM TO BE SOLVED: To provide a curable composition of which the storage stability of the main ingredient is good even when carbon black is used as a reinforcement for improving the mechanical strengths of the cured item and which has a good curability even after the storage of the main ingredient and is suitable to be used as a sealing material for double-layered glass, vehicle window frames, etc., having sufficient rupture strength and hardness. SOLUTION: This curable composition comprises (a) a polymer having at least two thiol groups per molecule, (b) a compound having at least two isocyanate groups per molecule, (c) carbon black, and (d-1) a filler mainly comprising silicic acid and/or a silicate and/or (d-2) an organic filler mainly comprising pulverized coal.
