PROBLEM TO BE SOLVED: To obtain an epoxy resin composition having excellent heat resistance, low water absorption, and low dielectric tangent even at a high-frequency of 1 GHz or more, and a low dielectric tangent material composed of a cured product of the resin composition. SOLUTION: The epoxy resin composition is characterized by comprising (A) an epoxy resin represented by formula (1) and (B) an ester of an aromatic polyvalent carboxylic acid and an aromatic hydroxy compound. ( In formula (1), G is a glycidyl group; Q and R are each a halogen atom, a 1-5C alkyl group, or an aryl group, wherein Q and R may be either the same as or different from each other; (n) is an integer of 0-8, and (m) and (p) are each an integer of 0-3.).
