A woody formed article, characterized as being produced by admixing a woody material W and, as a binding agent, a fibrous and/or ribbon shaped thermoplastic resin R which is easy to be intertwined with the woody material W, and molding the resultant mixture. The thermoplastic resin R is preferably admixed in a state of being heated and melted. A method for producing a woody formed material, characterized in that it comprises providing a mat M of a raw material mixture Mx of a woody material W and a fibrous and/or ribbon-shaped thermoplastic resin R and subjecting the mat M to heat pressing, or comprises, in admixing the woody material W with the above fibrous thermoplastic resin R, stretching and thinning the resin R by means of a hot wind and/or a cold wind pressure, and admixing homogeneously it with the woody material W by utilizing a negative pressure zone due to the hot wind and/or the cold wind, to prepare a mat M of a raw material mixture Mx, and then subjecting the mat M to pressing.
