PROBLEM TO BE SOLVED: To provide an epoxy resin composition for a fiber-reinforced composite material with excellent impregnation into a reinforcing fiber because of low viscosity, and low in a linear expansion coefficient of an obtained cured object, and the fiber-reinforced composite material of high Vf (fiber content by volume) excellent in surface smoothness, using the same. SOLUTION: This epoxy resin composition for the fiber-reinforced composite material contains at least an epoxy resin A and a curing agent B, and the epoxy resin A contains 30-70 wt.% of prescribed epoxy resin A1, and 70-30 wt.% of bisphenol-F type epoxy resin A2.
