To provide a two-component curable resin composition which has excellent workability with low viscosity and whose cured product is excellent in mechanical properties and weather resistance.SOLUTION: The two-component curable resin composition contains a component (A) and a component (B). As the component (A), an oxyalkylene-based polymer (A-1) containing a hydrolyzable silyl group and a (meth)acrylate polymer (A-2) containing no hydrolyzable silyl group are contained. As the component (B), a divalent tin compound (B-1) and an amine compound (B-2) are contained.SELECTED DRAWING: None 【課題】低粘度で作業性に優れ、かつ、硬化物は、機械物性および耐候性に優れた２成分型硬化性樹脂組成物を提供する。【解決手段】（Ａ）成分と（Ｂ）成分を含む２成分型硬化性樹脂組成物であって、前記（Ａ）成分として、加水分解性シリル基を含有するオキシアルキレン系重合体（Ａ−１）及び加水分解性シリル基を含有しない（メタ）アクリル酸エステル重合体（Ａ−２）を含み、前記（Ｂ）成分として、２価の錫化合物（Ｂ−１）及びアミン化合物（Ｂ−２）を含む、２成分型硬化性樹脂組成物である。【選択図】なし
