Abstract: PURPOSE:To obtain a decorative surface of hues changing three-dimensionally or dynamically according to conditions by forming, in parallel, patterns consisting of many fine grooves appearing and disappearing according to incident angles of light or visual angles on a film formed on the front surface of a metallic material. CONSTITUTION:The surface of the metallic material is subjected several anodic oxidation treatments. Optical path differences are generated between the reflected light atop the formed metal oxide layer and the reflected light by the metallic surface, by which the interference colors meeting the optical path differences are generated. Contour shapes of elements constituting the patterns are transferred on the front surface of this anodically oxidized film. The transfer diagrams of the respective elements are formed by inscribing many fine grooves extending in the same direction in a desired axial line 12 and working these lines to rugged surfaces paralleling at microintervals. The surface of the metallic material is otherwise worked to the rugged surface and thereafter, the anodically oxidized film is formed thereon.
