PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition useful mainly for applications for optical components and electronic components that is polymerization-curable in a short time by irradiation with an active energy ray to give a cured product of a high refractive index excellent in transparency, chemical resistance, flame retardancy and adhesion. SOLUTION: The active energy ray-curable resin composition comprises an epoxy (meth)acrylate compound (A) obtained by an addition reaction of (meth)acrylic acid to an epoxy compound that is obtained by an addition polymerization reaction of a phenolic compound represented by general formula (1) (wherein X is a hydrogen atom or a bromine atom; and p and q are each an integer of 0-4) to an epoxy resin having at least two glycidyl groups and a plurality of aromatic rings in one molecule and has a molecular weight of at most 2,000 and an epoxy equivalent of 450-900 g/equivalent, an unsaturated group-bearing compound (B) and a photopolymerization initiator (C).
