PROBLEM TO BE SOLVED: To provide a method for molding a resin article having a warp stripe, which makes it possible to form a warp stripe pattern by extrusion of a synthetic resin whereby an image of a cap piece accompanied with a conventional resin article can be removed to improve its decorative characters and appearance. SOLUTION: A melted resin extruded is molded into an outer surface of a resin article in a molding hole 15 of a molding die 13, while recessed ditches are formed in the outer surface of the body of this resin article by a projecting strip 23 in an inner periphery of the molding hole 15, and then a resin C having a different color from the body of the resin article is filled in the above recessed ditches of the moving body of the resin article, and finally an outer diameter of the resin article as well as the outer surface of the resin C having the different color are finished in a finishing hole 18 of a finishing die 14.
