PROBLEM TO BE SOLVED: To provide a curable composition having good hardenability as well as good physical properties in tension (high strength, high elongation, and high hardness). SOLUTION: The curable composition comprises (A) a polyoxyalkylene polymer having a group represented by formula (1):-SiX<SB>3</SB>(wherein X represents a hydroxyl group or hydrolyzable group; and three Xs may be mutually same or different) as a silicon-containing group which can be cross-linked by forming a siloxane bond; (B) a straight-chain polyoxyalkylene polymer having a group represented by formula (2):-SiR<SP>1</SP>X<SB>2</SB>(wherein R<SP>1</SP>represents any of a 1-20C alkyl group, a 6-20C aryl group, a 7-20C aralkyl group and a triorganosiloxy group represented by (R')<SB>3</SB>SiO-, wherein R' is a 1-20C hydrocarbon group and three R's may be same or different; X is the same as described above; and two Xs may be same or different) as a silicon-containing group which can be cross-linked by forming a siloxane bond; and (C) a polyoxyalkylene polymer with one or more branched chains, having a group represented by formula (2):-SiR<SP>1</SP>X<SB>2</SB>(wherein R<SP>1</SP>and X are same as described above) as a silicon-containing group which can be cross-linked by forming a siloxane bond.
