PROBLEM TO BE SOLVED: To provide a curable composition which can obtain a cured product having excellent adherence (elongation and peeling strength) and high shear strength and has a high curing rate. SOLUTION: The curable composition comprises a curable material (a1) of at least one polymer (a1) obtained by modifying a polyoxyalkylene polyol having 4 or more hydroxyl groups so as to effect conversion of a hydroxyl group to a group (X1) having a group represented by formula (Y1): -Si(OCH<SB>3</SB>)<SB>3</SB>, a curable material (a2) of at least one polymer (a21) obtained by modifying a polyoxyalkylene diol so as to effect conversion of a hydroxyl group to a group (X) having a group represented by formula (Y): -Si(OR)<SB>3</SB>(wherein R is a 1-6C organic group) or the like, wherein the ratio of the group (X1) among the groups (X) present in the curable material (a2) is 50 mol% or more, and a curing catalyst (b).
