摘要
Provided are an epoxy resin composition, a prepreg, a resin sheet, and a carbon fiber-reinforced composite material, which have excellent heat resistance, a high elastic modulus, low water absorption, and flame resistance. This epoxy resin is a para-cresol novolac epoxy resin represented by general formula (1), wherein the content of a component represented by n=1 as measured by gel permeation chromatography is at least 0.1% by area and less than 10% by area, and the content of a component represented by n=2 as measured by gel permeation chromatography is at least 0.1% by area and less than 40% by area. (In the formula, each of the plurality of R's independently represents a C1-6 alkyl group, n represents a real number of 1-10, and G represents a substituted or unsubstituted glycidyl group.)
