Provided is carbon fiber-reinforced composite material having excellent flame retardancy, accelerating hardenability, heat resistance and mechanical property, also, an epoxy resin composition suitable for making the fiber-reinforced composite material, prepreg, carbon fiber-reinforced composite material and electronic-electric component casings are provided. The epoxy resin composition is characterized by containing the following constituents: [A] epoxy resin composition containing 50 mass% or more of the compound represented by formula (I), [B] organic nitrogen compound hardener, [C] phosphoric acid ester and [D] phosphazene. (In the formula, R1, R2 and R3 represent hydrogen atom or methyl group; n represents an integer of 1 or more.) |
