PURPOSE: To provide a manufacturing method of a prepreg, in which cut dust is prevented from scattering, and of a metal-clad laminated sheet having no striking mark thereon. CONSTITUTION: A semi-cured prepreg 1, which is prepared by infiltrating a resin in a base material, is cut to a specified size and, after that, the surface of the resultant prepreg 1 is rinsed with water. The rinsing of the prepreg 1 is performed by passing it in a water tank under the state being placed on a belt conveyor 4. Thus, cut dusts adhered to the surface of the prepreg 1 are removed. A body to be pressed, which is prepared by laminating prepregs to one another so as to obtain a laminate and then a metal foil is arranged on the outermost layer of the laminate, is pressed under heat. Since the prepreg 1, from which cut dusts are removed, is employed, no cut dust scatters upon forming under heat and pressure. |
