PROBLEM TO BE SOLVED: To provide a curable epoxy resin composition capable of forming a cured product having high heat resistance and high light resistance, capable of maintaining an advantageous dispersion state of inorganic fine particles even when the composition is heated, and having a low viscosity and advantageous workability.SOLUTION: This curable epoxy resin composition includes an alicyclic epoxy compound, core-shell-type acrylic polymer particles having a solubility parameter (by the Fedors method) of 19.5 to 21.5 [MPa], and inorganic fine particles having an average particle diameter of 30 μm or less and a specific gravity of 10 g/cmor less, wherein the glass transition temperature of an acrylic polymer constituting a core of the core-shell-type acrylic polymer particle is 60 to 120°C; the glass transition temperature of an acrylic polymer constituting a shell of the core-shell-type acrylic polymer particle is 60 to 120°C; and the content of the core-shell-type acrylic polymer particle is 1 to 30 pts.wt. based on 100 pts.wt. of the alicyclic epoxy compound. |
