(57) [Problem] To provide a curable composition having a high curing rate. SOLUTION: (A) Silyl group-containing ethylene / α-olefin / non-conjugate having a structural unit derived from a norbornene compound having a terminal vinyl group which is a non-conjugated polyene and having a hydrolyzable silyl group in the molecule. As a polyene random copolymer rubber, and (B) a curing catalyst, a compound represented by the formula: Q 2 Sn (OZ) 2 or [Q 2 Sn (OZ)] 2 O (In the formula, Q represents a monovalent hydrocarbon group having 1 to 20 carbon atoms, and Z represents a monovalent hydrocarbon group having 1 to 20 carbon atoms or can form a coordination bond to Sn inside itself. A curable composition comprising a compound represented by the following formula: |
