Beschreibung
Zusammenfassung:	A problem addressed by the present invention is to provide a technology in production of a prepreg and to enhance the production efficiency, in which the technology allows the arrangement property and rectilinearity of reinforcing fibers to be well maintained and allows any resin to be applied stably at a high speed. A main object of the present invention is to produce a prepreg by a method of producing a prepreg, in which the method includes: discharging a molten resin in planar form to form a resin film, and applying the resin film 2 onto a reinforcing fiber sheet 1a conveyed continuously, wherein the reinforcing fiber sheet 1a is conveyed substantially in the horizontal direction, and wherein an angle made between the discharge direction of the resin and the conveyance direction of the reinforcing fiber sheet 1a is 80°or less.
