A prepreg (10) is provided with: a reinforcing fiber layer (3) that comprises reinforcing fibers (1) and a resin composition (2) that is used to impregnate the area between the reinforcing fibers and that comprises (A) a benzoxazine resin, (B) an epoxy resin, and (C) a curing agent that is represented by formula (C-1); and surface layers (6a, 6b) that are provided on the surface of the reinforcing fiber layer (3) and that comprise (A) the benzoxazine resin, (B) the epoxy resin, (C) the curing agent that is represented by formula (C-1), and (D) polyamide resin particles (4) having an average particle size of 5-50 [mu]m. The polyamide resin particles (4) include polyamide 12 resin particles or polyamide 1010 resin particles. (In formula (C-1), R1, R2, R3, and R4 each represent a hydrogen atom or a hydrocarbon group. When R1, R2, R3, or R4 is a hydrocarbon group, said hydrocarbon group is a straight-chain or a branched alkyl group having a carbon number of 1-4, or the adjacent R1 andR3 or the adjacent R3 and R4 are bonded and form a substituted or unsubstituted aromatic ring having a carbon number of 6-10 or a substituted or unsubstituted alicylic structure having a carbon number of 6-10. x represents 0 or 1.)
