PURPOSE:To observe a display part for characters or the like which is positioned on the surface of a sticking object to which a hologram seal is to be sticked by forming the hologram seal only as a simple transparent substance in a range other than a regenerative angular range. CONSTITUTION:The hologram seal 1 is constituted of a hologram forming layer 2, a transparent hologram 5 consisting of a transparent thin film layer 4 laminated on a hologram forming part 3 of the hologram forming layer 2, an adhering layer 6, an anchor layer 7, an oversheet 8, and a protection sheet 9. The refractive index of the layer 4 is different from that of the layer 12. The refractive index of the layer 4 may be larger or smaller than that of the layer 2, the difference of the refractive indexes is preferably >=0.1, and the difference >=1.0 is optimum.
