The invention relates to a method for surface treatment of a weather strip, by which a surface appearance almost identical to an embossing process is obtained in a simplified way without requiring any post-treatment by, for example, an embossing roll, wherein a thin film compressed and deformed by causing thermoplastic resin powder grains 5, which are mixed with thermoplastic base resin 4 and are not completely melted at an extrusion molding temperature, to pass through a flow path 6 of die 1, is extrusion-molded on the surface of glass run 2, and the thin film portion is applied as a sliding plane 3 for door glass.
