PURPOSE:To improve workability and lower manufacturing cost and contrive the improvement of the strength as well as the deep drawing property of a molded body by a method wherein the aggregated body of material having a low density is formed by laminating the lower aggregated layer of wooden series molding material, an intermediate sheet-type fiberous structure and the aggregated layer of upper wooden series molding material sequentially. CONSTITUTION:In case the aggregated body B2 of material is formed by a aggregated body manufacturing device 20 by employing wooden series molding material B1 obtained by adding wood fibers with binding agent including synthetic resin and mixing them, a switching valve 28 is operated to supply air into a vessel 24 for dispersing and form the stream of air to a vessel 22 for laminating while the material B1, supplied into a sprayer 23, is dispersed within a predetermined range to laminate it. A sheet-like fiberous structure F s set on the aggregated layer of the material B1 under an intermediate stage and, successively, the material B1 is laminated on the structure F. The switching valve 28 is operated by a height sensor 26 and when all of the sensors detect the lamination of the material B1, the supply of the material B1 and air is stopped and the forming of the aggregated body B2 of material is finished. The compression molding of the aggregated body B2 of the material is effected by employing a hot press molding type molding mold 35 to mold a wooden series molded body M1.
