PROBLEM TO BE SOLVED: To provide a method for producing a prepreg which has a smooth surface and little surface defects.SOLUTION: The method for producing a prepreg comprises: an impregnation liquid production step where the impregnation liquid is produced by subjecting a resin composition 10 comprising a filler and a resin to a centrifugal treatment; and an impregnation step where a substrate is impregnated with the impregnation liquid obtained by the liquid production step. Further, in the impregnation liquid production step, the resin composition during centrifugal treatment preferably flows in a thin film-like form. The centrifugal treatment is preferably performed under a reduced pressure of 0.5 MPa or less and at a revolution of 400 rpm or less. |
