    Abstract: The present invention relates to an epoxy resin composition which comprises a phosphorus-containing modified epoxy resin (A) consisting of a compound (a) represented by Formula (a); a novolak epoxy resin (B); a hardener (C) for epoxy resins; and a metal hydroxide (D), wherein the content in mass % of the phosphorus-containing modified epoxy resin (A), CA, and the content in mass % of the metal hydroxide (D), CD, relative to the total amount of the epoxy resin composition, satisfy the following Formulas (1), (2), and (3): (1) 2.5CA+CD≧5; (2) 6≦CA≦40; and (3) 3≦CD≦30. This epoxy resin composition can give a composite material which has excellent flame retardancy even when neither a halogenated flame retardant, nor red phosphorus, nor a phosphoric acid ester is contained therein. According to the invention, it is also possible to provide a prepreg and a fiber-reinforced composite material obtained using the prepreg.
