A moisture curable polymer and a curable composition having superior curability are provided. A polymer having a silicon group represented by the general formula: —SiFaR1bZc (wherein, R1 represents any one of a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, or an organosiloxy group represented by R23SiO— (R2 is each independently, a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms). Z is a hydroxyl group or a hydrolyzable group other than fluorine. a is any one of 1, 2, or 3; b is any one of 0, 1, or 2; c is any one of 0, 1, or 2; and a+b+c is 3. When b or c is 2, two R1 or two Z may be each the same or different) and a curable composition including this polymer, and a sealant and an adhesive in which the curable composition is used.
