PROBLEM TO BE SOLVED: To provide an epoxy resin composition which uses a suitable alkylated ester to be able to control gelling and curing time in such a manner that it is suitable for molding a fiber-reinforced composite material in a high temperature curing system, and has heat resistance and useful mechanical physical properties, to provide a fiber-reinforced composite material having high heat resistance and excellent mechanical strength, and to provide its manufacturing method.SOLUTION: The epoxy resin composition includes a constituent (A) which is an epoxy resin having two or more epoxy groups in one molecule, a constituent (B) which is a liquid anionic polymerization initiator which is liquefied at 25°C, and a constituent (C) which is toluenesulfonic acid ester, wherein the viscosity at 70°C is in a range of 0.001-1 Pa s. |
