PROBLEM TO BE SOLVED: To provide a reinforced fiber prepreg obtained at inexpensive cost, scarcely having surface defect and having good quality appearance and to provide a method for producing the prepreg. SOLUTION: The reinforced fiber prepreg material is obtained by carrying a release paper on a reinforced fiber prepreg obtained by impregnating a reinforced fiber sheet with a matrix resin. In the reinforced fiber prepreg material, the release paper has a clay coat layer on a superposition side of the reinforced fiber prepreg, and crack defects of the reinforced fiber prepreg surface are≤10 numbers/100 m<SP>2</SP>.
