1. An epoxy resin composition comprising an epoxy resin and an epoxy resin curing agent,
wherein the epoxy resin curing agent comprises an amine composition or a modified product thereof,
wherein the amine composition comprises:
bis(aminomethyl)cyclohexane (A),
a compound (B) of at least one selected from the group consisting of a compound (1-1) and a compound (1-2) represented by the following formulas:, and
a compound (C) of at least one selected from the group consisting of a compound (2-1) and a compound (2-2) represented by the following formulas:, wherein a mass ratio of the component (B) to the component (C) [(B)/(C)] is from 1.0 to 5.0, and
wherein the epoxy resin curing agent is present in the epoxy resin composition at an amount such that a ratio of the number of active hydrogen atoms in the epoxy resin curing agent to the number of epoxy groups in the epoxy resin [(number of active hydrogen atoms in epoxy resin curing agent)/(number of epoxy groups in epoxy resin)] is from 1/0.5 to 1/2.
