Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a forgery prevention thread having high forgery preventing effect, and a forgery preventing paper and a truth judging method using the thread. SOLUTION: The forgery prevention thread 10 is incorporated into a forgery prevention paper to use it. In the paper, ferromagnetic two or more layers 15 are formed on a base body consisting of a resin film, and at least one layer out of the ferromagnetic layers has a pattern. The ferromagnetic layers can be formed by a vacuum depositing method or a printing method, and a non- magnetic layer 161 may be played between ferromagnetic layers. Further, the paper may have an optical diffraction lattice or a hologram pattern. The forgery prevention paper is characterized in that the forgery prevention thread 10 is incorporated in it.
