    摘要: Disclosed is a method of producing a fiber-molded hollow article by using a papermaking mold (2) composed of splits (21, 22) which are joined to form a cavity (20) having two openings (20a, 20b) connecting with the outside and an expandable pressing member (3) adapted to be placed in the cavity (20). The method comprises the steps of immersing each of the splits (21, 22) before being joined in a fiber slurry to form a fiber preform (10a, 10b), joining the splits (21, 22) each having the fiber preform (10a, 10b) formed thereon while placing the pressing member (3) in the cavity (20), and molding and dewatering a molded article (1) in the papermaking mold (2).
