The present invention provides a curable epoxy resin composition capable of obtaining a cured product having high heat resistance, low water absorption, and high strength. [Solution] (A) a liquid epoxy resin, (B) an aromatic amine-based curing agent, and (C) a thermosetting resin composition containing a cyclic carbodiimide compound, (B) The compounding quantity of an aromatic amine type hardening | curing agent is 0.7-1 for all amino groups in (B) aromatic amine type hardening | curing agent with respect to 1 equivalent of all the epoxy groups in (A) liquid epoxy resin. The thermosetting epoxy in an amount of 0.5 equivalent and (C) the cyclic carbodiimide is 2 to 50 parts by mass with respect to 100 parts by mass in total of the (A) epoxy resin and the (B) aromatic amine curing agent. Resin composition. [Selection figure] None |
