1. A method of producing a prepreg, comprising:
discharging a molten resin in planar form from a slit to form a resin film, and forming a film-shaped object in a space into which the molten resin is discharged,
applying said resin film onto a reinforced fiber sheet conveyed continuously,
wherein said reinforced fiber sheet is conveyed substantially in the horizontal direction,
wherein an angle made between the discharge direction of the molten resin and the conveyance direction of said reinforced fiber sheet is 80° or less; and
wherein an air flow is applied to the edge portion of said film-shaped object formed in the space in the width direction from a front of the film-shaped object so that the edge portion of the resin film can be expanded when said reinforced fiber sheet is coated with said resin film, and
wherein a distance between a center of a discharge line and said reinforcing fiber sheet is 3 mm or more and 18 mm or less; and
wherein a viscosity of the molten resin is 21 Pa·s or less.
