PROBLEM TO BE SOLVED: To provide a synthetic resin type multilayered extrusion molded object excellent in woody feeling and weatherability. SOLUTION: The multilayered extrusion molded object, which contains a surface layer material containing a colored resin excellent in weatherability as a base resin and a substrate, is formed by subjecting the surface of the surface layer material to sanding treatment. A seed resin containing a colorant, of which the MFR value is lower than that of the base resin of the surface layer material, is mixed with the base resin and the resulting surface layer resin mixture is subjected to extrusion molding to form a pattern due to the seed resin in the surface layer material. Grain printing or clear coating is applied to the surface of the surface layer material subjected to sanding treatment to provide the multilayered extrusion molded object. COPYRIGHT: (C)2004,JPO
