Beschreibung
Zusammenfassung:	Provided is a prepreg that can be cured in a short time even at a low temperature, and can obtain a fiber-reinforced composite resin molded article having excellent mechanical properties such as flexural modulus, bending strength, and breaking strain, and excellent heat resistance. The prepreg of the embodiment includes an epoxy resin composition and a reinforcing fiber, in which the epoxy resin composition includes a component (A): an oxazolidone epoxy resin, a component (B): a novolac epoxy resin, a component (C): a urea compound, and a component (D): a curing agent, and with respect to a total mass of all epoxy resins included in the epoxy resin composition, a content of the component (A) is 40% to 70% by mass and a content of the component (B) is 15% to 40% by mass.
