[PROBLEMS] To improve the curing speed and adhesiveness of a curable composition containing a saturated hydrocarbon polymer having a reactive silicon group as a main component. (A) A saturated hydrocarbon polymer having at least one silicon-containing group which has a hydroxyl group or a hydrolyzable group bonded to a silicon atom and can be crosslinked by forming a siloxane bond; B) tetravalent tin compounds, (C) General formula (1), R 1 a Si (OR 2 ) 4 -a (1) (wherein, R 1 and R 2 each independently have 1 to 1 carbon atoms. 20 substituted or unsubstituted hydrocarbon groups. A is 0, 1, 2, or 3. A curable composition comprising a silicon compound represented by the formula (1): |
