PROBLEM TO BE SOLVED: To obtain a low density molded article which has an excellent cushioning property and excellent recyclability, by molding, dehydrating and drying a slurry containing recycled synthetic fibers as a raw material. SOLUTION: This low density molded article is obtained by injecting a slurry 16 comprising recycled synthetic fibers having a number-average fiber length of <=50 mm into a mold container 10 from an upper guide 15, simultaneously sucking water from the lower suction port 14 of the container to accumulate the raw material fibers, slightly compressing the accumulated fibers with the upper mold of a press machine to smoothen the upper surface of the molded article, blowing hot air to dry the molded article, and then taking out the molded article from the container mold 10. The recycled synthetic fibers comprises fibers obtained from synthetic fiber-containing wastes such as bedding or carpets, or fibers produced from synthetic resin wastes, such as pet bottles, except the fibers as a raw material.
