Zusammenfassung:	To provide a low-viscosity curable resin composition capable of giving a cured product excellent in impact resistance.SOLUTION: The curable resin composition contains core-shell type rubber particles (A), a radically polymerizable compound (B) having one or more radically polymerizable functional groups in the molecule, and a radical polymerization initiator (C). The core-shell type rubber particles (A) each have a core layer and a shell layer which contains a polymer having a heterocyclic structure. The content of the radically polymerizable compound (B) is 50 mass% or more and 99 mass% or less based on 100 mass% of the total of all components of the curable resin composition. The radically polymerizable compound (B) contains 2 mass% or more and 70 mass% or less of a radically polymerizable compound (b-1) having a molecular weight of 500 or more.SELECTED DRAWING: None 【課題】耐衝撃性に優れた硬化物を得ることができる、低粘度の硬化性樹脂組成物を提供する。【解決手段】コアシェル型ゴム粒子（Ａ）と、分子内に１個以上のラジカル重合性官能基を有するラジカル重合性化合物（Ｂ）と、ラジカル重合開始剤（Ｃ）とを含有する硬化性樹脂組成物であって、コアシェル型ゴム粒子（Ａ）は、コア層と、複素環構造を有する重合体を含有するシェル層を有し、ラジカル重合性化合物（Ｂ）の含有量は、硬化性樹脂組成物の全成分の合計を１００質量％とした場合、５０質量％以上９９質量％以下であり、ラジカル重合性化合物（Ｂ）は、分子量５００以上のラジカル重合性化合物（ｂ−１）を２質量％以上７０質量％以下含有する硬化性樹脂組成物。【選択図】なし
