摘要： Provided is a resin composition that is capable of producing a cured product having excellent environmental suitability, high strength, and excellent flame retardancy, and that is suitably usable as a matrix resin for fiber-reinforced plastics. A resin composition contains (A) an epoxy resin, (B) a cyanate resin, (C) an aromatic amine curing agent that is liquid at 25°C, and (D) a phosphorus-containing compound represented by formula (1). Preferably, in formula (1), R 1 and R 2 each independently represent an alkyl group or an aryl group, and X and Y are an oxygen atom.
