A method of producing a pulp molded article comprising the steps of assembling splits ( 10, 11 ) each having a suction passageway and a papermaking screen ( 5 ) into a papermaking mold ( 1 ), filling the cavity of the papermaking mold ( 1 ) with a pulp slurry, discharging the liquid component of the pulp slurry through the suction passageway to deposit pulp fiber on the inner side of the papermaking screen ( 5 ) into an undried wet molded article, and dewatering the undried molded article deposited on the inner side of the papermaking screen ( 5 ), wherein the splits ( 10, 11 ) each have a large number of flow passageways ( 2 ) for feeding a purging fluid for cleaning the papermaking screen ( 5 ), and the purging fluid is ejected from the outer side of the papermaking screen ( 5 ) toward the cavity through the flow passageways ( 2 ) during the filling with the pulp slurry.
