PROBLEM TO BE SOLVED: To obtain a curable composition which is excellent in chemical resistance such as acid resistance even when it contains an oxypropylene polymer having a broad molecular weight distribution. SOLUTION: The curable composition contains (A) the oxypropylene polymer produced by polymerization using a compound metal cyanide complex catalyst or a phosphazene catalyst, containing at least one silicon-containing group containing a silicon atom bonded with a hydroxy group or a hydrolyzable group, and having an Mw/Mn ratio of above 1.60 and (B) an antioxidant.
