Provided is a curable epoxy resin composition which has high heat resistance, light resistance and thermal shock resistance, and which provides a cured product, in particular with excellent reflow resistance after moisture absorption. This curable epoxy resin composition is characterized by comprising a cycloaliphatic epoxy compound and core-shell type acrylic polymer particles with a solubility parameter (Fedors method) of 19.5 to 21.5 [MPa1/2], and is characterized in that the acrylic polymer constituting the core of the core-shell type acrylic polymer particles has a glass transition temperature of 60 to 120°C, the acrylic polymer constituting the shell thereof has a glass transition temperature of 60 to 120 °C, the content of the core-shell type acrylic polymer particles is 1 to 30 parts by weight with respect to 100 parts by weight of the cycloaliphatic epoxy compound, and viscosity at 25°C is 60 to 6,000 mPa.s. |
