PROBLEM TO BE SOLVED: To provide a curable composition comprising a vinylic polymer having alkenyl groups at the terminals in high proportion as an essential component. SOLUTION: The composition essentially comprises (A) a vinylic polymer having alkenyl groups represented by general formula 1: CH<SB>2</SB>=C(R<SP>1</SP>)- (wherein, R<SP>1</SP>is hydrogen or a methyl group) at the terminals, and (B) a hydrosilyl group-containing compound. The vinylic polymer preferably has <1.8 value of the ratio of the weight average molecular weight to the number average molecular weight measured by a gel permeation chromatography.
