The present invention is a curable composition comprising:

(A) a polyoxyalkylene polymer having a silicon-containing group crosslinkable by forming a siloxane bond;(B) a polyoxyalkylene plasticizer whose main chain contains 5 wt % or more of an oxypropylene-derived repeating unit and has one or more groups, at an end thereof, selected from the group consisting of an —OH group, a group represented by the formula:—OR9 (wherein R9 is a substituted or unsubstituted C1-20 hydrocarbon group),and a group represented by the formula:—NR102 (wherein R10 is each independently a hydrogen atom, or a substituted or unsubstituted C1-20 hydrocarbon group).
