PROBLEM TO BE SOLVED: To provide a preventive structure for sheet forgery capable of effectively preventing a forgery by a recent high performance copier, a high performance scanner or the like. SOLUTION: A strip-like flocked fabric portion 4 is provided partly on a gift certificate surface 1a. The portion 4 is formed by directly flocking the surface 1a or provided on the surface 1a by utilizing a flocking label formed separately independently from the certificate 1. In a true gift certificate 1, there is obtained a stereoscopic sense due to an uneven surface as the portion 4 is seen to be protruded by hairs 4a of the flocked portion 4 or a sense of quality as warmth or flexibility of hairs 4a of the portion 4 is observed. When the certificate 1 is copied as a forgery, it does not have the stereoscopic sense of the uneven surface and only a sense of cold quality without hair is felt. Accordingly, a truth or a forgery is decided from the stereoscopic sense of the uneven surface of the portion 4, the sense of quality or the like. |
