A hologram foil is provided to expose various patterns, which are printed by a fluorescent substance, through illumination of specific wavelength light, thereby effectively preventing forgery or falsification of cards, securities, or identification cards. A transparent deposition layer(40) is formed on a hologram layer(30) by PDV(Physical Vapor Deposition) or CVD(Chemical Vapor Deposition). The transparent deposition layer is formed of a mixture of one or more selected from zinc sulfide, magnesium fluoride, magnesium oxide, calcium fluoride, aluminum oxide, silicon dioxide, titanium dioxide, zirconium dioxide, cerium dioxide, zinc dioxide, and titanium oxide. The transparent deposition layer has a thickness of 200-600 angstroms. A fluorescent substance-printing unit(50) emits light consisting of wavelength of a visible light band when the fluorescent substance-printing unit is exposed to light consisting of wavelength of no more than 450 nm or no less than 650 nm. An adhesive layer(60) offers an adhesive force with an adherend member.
