Summary:To provide a curable composition excellent in workability and also excellent in mechanical properties and weather resistance of a cured product, and to provide a sealing material composition.SOLUTION: A curable composition contains an oxyalkylene-based polymer (A) having a reactive silyl group and a (meth)acrylic polymer (B). The (meth)acrylic polymer (B) has 0.01 meq/g or more and 0.11 meq/g or less of double bonds in the molecule. The (meth)acrylic polymer (B) does not contain a reactive silyl group in the molecule.SELECTED DRAWING: None 【課題】作業性に優れ、かつ、硬化物の機械物性及び耐候性にも優れる硬化性組成物及びシーリング材組成物を提供する。【解決手段】反応性シリル基を有するオキシアルキレン系重合体（Ａ）、及び（メタ）アクリル系重合体（Ｂ）を含む硬化性組成物であって、前記（メタ）アクリル系重合体（Ｂ）は、分子中に二重結合を０．０１ｍｅｑ／ｇ以上、０．１１ｍｅｑ／ｇ以下有するようにする。また、（メタ）アクリル系重合体（Ｂ）は、分子中に反応性シリル基を含まない。【選択図】なし
