    摘要: A prepreg is provided that has excellent processability and handleability and that can be processed into a cured product with high heat resistance. Also provided is a method to produce such a prepreg in an industrially advantageous way without being restricted by the types and contents of the matrix resin components used. The prepreg includes at least components [A] to [D] as given below and a preliminary reaction product that is a reaction product of the component [B] and the component [C], at least one surface resin in the prepreg having a storage elastic modulus G′ in the range of 1.0×103 to 2.0×108 Pa as measured at a temperature of 40° C. and an angular frequency in the range of 0.06 to 314 rad/s: [A] carbon fiber, [B] epoxy resin comprising a m- or p-aminophenol epoxy resin [b1] and either a glycidyl ether epoxy resin or a glycidyl amine epoxy resin [b2] that has two or more glycidyl groups in a molecule, [C] curing agent, and [D] thermoplastic resin.
