摘要： Provided is a curable epoxy resin composition capable of forming a cured product that has heat resistance, light resistance, and thermal shock resistance at high levels and particularly offers excellent reflow resistance after moisture absorption. The curable epoxy resin composition includes an alicyclic epoxy compound (A), a monoallyl diglycidyl isocyanurate compound (B) represented by Formula (1), a curing agent (C), and a curing accelerator (D). The composition includes methylnorbornane-2,3-dicarboxylic anhydride as an essential component of the curing agent (C) and has a succinic anhydride content of 0.4 percent by weight or less based on the total amount of the curing agent (C) :

wherein R 1 and R 2 are identical or different and each represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.
