<p>PROBLEM TO BE SOLVED: To improve both a forgery prevention effect and an eye catch effect, especially, to secure continuity in the visible area of a light-scattering pattern formed from fine ruggedness on the surface by enabling precise and various expressions in the pattern. SOLUTION: Each of fine recessed or projecting parts formed on the surface of a base material is defined as a light-scattering element which is to become minimum units constituting the light-scattering body. As a light-scattering element, a plurality of elements in different sizes are arrayed, and the light- scattering body is configured. Also while properly setting a light-scattering property for each pixel, a plurality of light-scattering bodies are arrayed on the surface of the base material as pixels, and the light-scattering pattern is constituted.</p> |
