Summary:PROBLEM TO BE SOLVED: To provide a carbon fiber-reinforced composite material comprising a matrix resin having high elongation and excellent heat resistance, and having excellent characteristics such as fatigue resistance, resistance to thermal crack, and heat resistance, and to provide a method for producing the composite material. SOLUTION: This method for producing the carbon fiber-reinforced composite material comprises a liquid epoxy resin composition capable of providing a cured product having >=4% tensile elongation at a room temperature when the composition is cured a the same condition as the molding condition of the carbon fiber-reinforced composite material, and having the glass transition temperature >=10 deg.C higher than the curing temperature. The carbon fiver- reinforced composite material is produced by using the method.
