A first parting film is held on a first flat laminating table in close contact with the first flat laminating table, and then wide prepregs are laid for plane lamination on the first parting film to form a large prepreg-laminate having a large area. A second parting film is held on a second flat laminating table in close contact with the second flat laminating table by suction, and then narrow prepregs to form a gridlike prepreg-laminate. The large prepreg-laminate is floated up by jetting air from the first flat laminating table is cut on a cutting table to obtain a prepreg-laminate skin. The gridlike prepreg-laminate is processed similarly to obtain a prepreg-laminate doubler. The prepreg-laminate skin and the prepreg-laminate doubler are carried from the cutting table to a laminating mold having a single-contour laminating surface so as to be superposed and are laminated to form a composite panel.
