PROBLEM TO BE SOLVED: To provide a curable composition giving cured products improved in residual tack and reduced in stickiness, within the physical property range having tensile characteristics and rubber elasticity required of sealing compositions for general architectural use. SOLUTION: The present invention provides the curable composition which comprises (I) 100 parts by weight of a reactive silicon group-containing polyether oligomer with the percentage of the number of reactive silicon groups to the number of molecular chain terminals as determined by<SP>1</SP>H-NMR analysis being not less than 85% and (II) 1 to 500 parts by weight of a plasticizer.
