The object of the present invention is to provide an extrusion molding article having an appearance resembling to natural timbers, and a method for producing the same. The molded article of resins by an extrusion molding is produced as follows: The glazed portion comprising at least a glazed face is produced with a resin material containing wood powder in which the resin is blended with the wood powder. The resin material containing wood powder comprises 20 to 40 parts of the wood powder having a particle size of 20 meshes or less and 0.5 to 4 parts of a blowing agent in 100 parts of a thermoplastic resin. The glazed face is formed by removing skin layers formed during the extrusion molding.
