PURPOSE: To provide an adhesive seal using a hologram useful to prevent forgery and identifying a forged article from a genuine article and having much decorativeness. CONSTITUTION: The forgery preventive adhesive seal 2 comprises a hologram layer 4 capable of reproducing an image by utilizing an incident light, a retro- reflecting material layer 6 for feeding back the incident light in an incident light entering direction, and an adhesive layer 8 for laminating an article to be sequentially laminated. In this case, the layer 4 reproduces a multiple exposure type in which rainbow hologram images of a two-dimensional image and a three-dimensional image are reproduced by emitting a white light from a specific direction at a specific angle, and the hologram image is erased or new Fourier transformed hologram image is reproduced by emitting a laser beam from a specific direction at a specific angle. The layer 6 has an interference substance layer made of a mica powder covering with an Li-Co-Ti composite oxide represented by a formula Li0.5-xCo0.5-x£Li0.5-xCoxTi1.5|O1 (0<X<0.1) for creating a colored interference color and transparent infinitesimal balls aligned and disposed on the substance layer.
