Abstract: PROBLEM TO BE SOLVED: To shorten the manufacturing cycle period of time by injecting a pulp slurry in a cavity after inserting an insertion member, which reduces the volume in the cavity, into the cavity when a pulp molded article is manufactured. SOLUTION: When this pulp molded article is manufactured, first, an insertion member 7 is inserted into a cavity 4 through a mouth section 6 of a die 1 comprising split dies 2 and 3. The insertion member 7 is equipped with a core 8 and a bag-form covering member 9, and the core 8 and the covering member 9 are fixed to a fixing plate 11. Then, a pressurized fluid is fed into the covering member 9 from a pressurized fluid feeding source, and the covering member 9 is preliminarily expanded to a specified size. Then, a pulp slurry is injected in the cavity 4 from an injection section 12 of the fixing plate 11, and the pulp fiber is accumulated on the internal surface of the cavity 4, and thus, a pulp layer 13 is formed. Then, a sucking and a dehydrating for the inside of the cavity 4 are performed. Continuously, the pressurized fluid is further fed in the covering member 9, and by the expanded covering member 9, the pulp layer 13 is pressed to the internal surface of the cavity 4.
