PROBLEM TO BE SOLVED: To provide a curable composition which comprises an alkoxysilyl group-containing vinylic polymer and whose surface is hardly stained, to provide a sealing material, and to provide an adhesive. SOLUTION: This curable composition comprises (a) a vinylic polymer having cross-linkable silyl groups represented by formula (1): -[Si(R<SP>1</SP>)<SB>2-b</SB>(Y)<SB>b</SB>O]<SB>m</SB>-Si(R<SP>2</SP>)<SB>3-a</SB>(Y)<SB>a</SB>[R<SP>1</SP>and R<SP>2</SP>are each an alkyl, an aryl, an aralkyl, or a triorganosiloxy; Y is OH or a hydrolyzable group, provided that, when two or more Y groups exist, the groups may be identical or different; (a) is 0 to 3; (b) is 0 to 2; (m) is an integer of 0 to 19, where (a)+(m)(b)≥1], at the terminals, wherein (a) the vinylic polymer has (b) a fluorine atom-having polymerizable monomer and/ or (c) a siloxane group-having polymerizable monomer as copolymerization components.
