PROBLEM TO BE SOLVED: To provide antifalsification paper affording maximum anti-falsification effects at a minimum cost. SOLUTION: The antifalsification paper is prepared by blending fibers detectable with a contact or a non-contact sensor in paper. In the antifalsification paper, the fiber surfaces are coated with an organic material containing a fluorescent or a phosphorescent substance. The center of the fibers is a conductor wire or a metal wire prepared from a material selected from the group consisting of copper, aluminum, iron, cobalt and a compound containing one or more of the same.
