| description | PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminate which exerts good fluidity and complicate shape-followability in molding and excellent mechanical characteristics with low variation and excellent dimensional stability when used as a fiber-reinforced plastic. SOLUTION: The method comprises cutting entirely a unidirectional prepreg substrate composed of a reinforcing fiber and a matrix resin to obtain a cut prepreg substrate, winding up the cut prepreg substrate, together with a tapered support, in a roll form, supplying both the wound cut prepreg substrate and the wound tapered support continuously from a feeding reel, pressingly sticking the cut prepreg substrate by a roller to laminate and winding, on a reel, the tapered support separated from the cut prepreg substrate. Substantially the whole of the reinforcing fiber constituting the cut prepreg substrate to be delivered to the feeding reel is in a cut form with lengths L in the fiber direction of 10-100 mm.
