Epoxy resin composition, a prepreg and carbon fiber reinforced composite material

Excellent tensile strength compressive strength, the epoxy resin composition which provides a suitable carbon fiber reinforced composite material as a structural material, and prepreg, provides a carbon fiber reinforced composite material. At least, [A]: an epoxy resin having a structure represented by formula (1), [B]: an amine type glycidyl group or ether type glycidyl group one or more, is liquid at 40 ° C. Epoxy resin, [C] : epoxy resin composition characterized in that it comprises a curing agent, and a prepreg using the same, a carbon fiber reinforced composite material. [Formula 1] (However Shikichu, R
