Abstract: Disclosed is a method for producing a prepreg, the prepreg having: a reinforcing fiber layer including reinforcing fibers and a resin composition containing component (A), component (B), and component (C), the reinforcing fibers being impregnated with the resin composition in between the fibers; and a surface fiber layer provided on the surface of the reinforcing fiber layer and including a fabric including polyamide fibers and a resin composition containing component (A), component (B), and component (C), the polyamide fibers being impregnated with the resin composition in between the fibers. The method for producing a prepreg includes a disposition step of disposing the fabric on the surface of a reinforcing fiber base material and an impregnation step of supplying a resin composition to the reinforcing fiber base material and impregnating the reinforcing fibers with the resin composition in between the fibers.
