A discrimination medium for objects by which counterfeiting can be prevented, authenticity of the article can be easily and reliably determined, and the production cost can be reduced is provided. In the discrimination medium, the support body 31 and the pattern 20 appear to be the same color when viewed from a specific angle (for instance, viewing from the front). On the other hand, when the viewing angle is increased, the color of the pattern 20 composed of a multilayer thin film changes by color shift, whereby the pattern 20 becomes a color different from the support body 31. <IMAGE> |
