The present invention relates to a surface treatment method of a plastic material, and a surface structure of a plastic material manufactured thereby. The surface treatment method of a plastic material comprises the following steps: forming a surface layer including at least one material selected among titanium, a titanium alloy, aluminum, an aluminum alloy, and oxide, nitride, and oxynitride thereof, on the surface of the plastic material to be less than a stoichiometric composition ratio; partially forming a porous anodizing film layer in the surface layer by anodizing the surface layer; and coloring an upper part of the porous anodizing film layer with a pigment, and sealing the same. The surface treatment method enhances surface strength of a plastic material, and alleviates non-uniformity continuously formed on the surface. Also, the surface treatment method imparts metallic properties to a plastic material, and can embody various, elegant, and uniform colors on the surface. |
