An extremely practical prepreg manufacturing device whereby a fiber body can be easily impregnated with a high-viscosity, low-concentration thermosetting resin using existing hot-melt method equipment, without having to use a solvent. In a prepreg manufacturing device for manufacturing a prepreg (5) by laminating and heating a resin sheet (4) formed by laminating a resin (3) with a release film (2), a resin sheet feeding mechanism (6) for feeding the resin sheet (4) laminated with a conveyed fiber body (1) comprises a release film feeding part (7) for feeding the release film (2), and a resin application part (8) for applying the resin (3) on the release film (2), the resin (3) containing a solvent. The resin sheet feeding mechanism (6) is configured so that the fiber body (1) is laminated with the resin sheet (4) formed by laminating the resin (3) with the release film (2), without the resin sheet (4) being formed into a roll shape.
