PROBLEM TO BE SOLVED: To provide a low-viscosity epoxy resin composition having excellent impregnating properties because of a small change in viscosity and having excellent productivity because of rapid curability at a low temperature such as about 100°C and to provide a fiber-reinforced composite material using the composition. SOLUTION: The epoxy resin composition comprises at least the following constituent elements (A) to (C). The amount of the constituent element (A) is 70-100 wt.% based on the whole epoxy resin and the amount of the constituent element (C) is 0.1-5 wt.% based on the whole epoxy resin. The constituent element (A) is a bisphenol F type epoxy resin having≤200 epoxy equivalents; the constituent element (B) is an aromatic polyamine which is liquid at room temperature and the constituent element (C) is a complex of a Lewis acid with a base.
