Abstract
To provide a low-viscosity curable resin composition capable of obtaining a cured product excellent in impact resistance. The curable resin composition contains core-shell type rubber particles, a radically polymerizable compound having one or more radically polymerizable functional groups in the molecule, and a radical polymerization initiator, and the core-shell type rubber particles have a core layer and a shell layer containing a polymer having an alicyclic hydrocarbon group in a side chain, and the radically polymerizable compound contains a radically polymerizable compound having a molecular weight of 500 or more in a ratio of 2 mass % to 70 mass %.
