Abstract

Provided are an epoxy resin exhibiting excellent heat resistance, a curable resin composition, cured products thereof, and a carbon fiber-reinforced composite material. This epoxy resin is represented by formula (1), wherein when the peak area of the compound represented by formula (2) is denoted as a, and the peak area of the compound represented by formula (3) is denoted as b in a chromatogram of high performance liquid chromatography, b/a is 0.012-0.050. (In formula (1), n is an average number of repetitions, and is a real number satisfying 1<n<15; X is independently a monovalent group represented by formula (a) or formula (b), and at least one X is a monovalent group represented by formula (a); and * binds to an oxygen atom.)
