CONSTITUTION:A hologram body 4 is mainly composed of a hologram forming layer 5 servicing as hologram and the protective layer 3. The protective layer 3 is installed on the surface and/or the interior of the hologram body 4, where the surface of the hologram body 4 means the upper and lower surfaces of the hologram body 4 (namely, the protective layer 3 is provided just like a protective layers and 3b), and the interior of the hologram body 4 means the space between the hologram forming layer 5 and a hologram effective layer 6, or the space between a basic film 7 and a hologram forming resin layer 8 if the hologram forming layer is multilayered.
