Abstract
A method of producing a fiber molded article using a pressing mold, includes inserting a first split and a second split into a slurry tank such that a fiber layer is formed on the first split and a fiber layer is formed on the second split, placing the pressing mold, which includes a solid elastic member and an inflatable elastic member configured to be inflated, onto the fiber layer on the first split, joining the first split and the second split such that a fiber molded article is formed from the fiber layer on the first split and the fiber layer on the second split, and dewatering and shaping the fiber molded article by pressing the fiber molded article by the solid elastic pressing member and the inflatable elastic pressing member.
