Abstract

Provision of a curable composition having good curability and adhesiveness by the use of a non-organotin catalyst.A curable composition containing an organic polymer (A) having a silicon-containing group crosslinkable by forming a siloxane bond, metal carboxylate (B), a silane coupling agent (C) free of an amino group, and an amino group-containing compound (D) in an amount corresponding to a weight ratio relative to (B) of 0-0.05, which contains, as the silicon-containing group of component (A), a silicon-containing group, wherein three hydrolyzable groups or hydroxyl groups are bonded to a silicon atom, as an essential component.
