Abstract
A method of manufacturing a molded wooden product includes the steps of: preparing a ligneous molding material by adding a binder essentially consisting of a synthetic resin and the like to wood fibers; adjusting the weight of the molding material in a fibrous state or in a state of being aggregated into a predetermined configuration; directly supplying the molding material to a shaping mold; shaping the outer periphery of the molding material by moving the shaping mold toward the center in conformity with the final external shape of a molded product; and hot compression molding the molding material, thereby obtaining a molded wooden product of a predetermined configuration.
