PURPOSE: To enable a hologram image to produce a three-dimensional image information and a visible information by building up on a base body at least a magnetic recording layer, a hologram layer and a conductive thin metal film layer successively.
CONSTITUTION: There are provided on a base body 2 at least a magnetic recording layer 3, a conductive thin metal film layer 4 and a conductive hologram layer 5. To protect the hologram layer 5, a conductive protective layer 6 is provided as required and may be colored. The magnetic recording layer 3 may be formed partially or entirely over the base body 2. The conductive thin metal film layer 4 may be as large as or larger than the magnetic recording layer 3. These layers may be built up using an adhesive agent as required. To form the base body 2, plastic such as polyvinyl chloride, polyester, polycarbonate, methylpolymethacrylate and polystyrene, papers and synthetic paper is used separately or in the combination thereof.
