PROBLEM TO BE SOLVED: To provide a hologram transfer sheet wherein a hologram layer which is difficult to forge or alter can be formed on a transfer-applied body. SOLUTION: This hologram sheet 1 comprises, as its main parts, a base material 11, an exfoliation layer 12, a hologram formation layer 13, a light reflection layer 14, and an adhesion layer 15. And, use of this hologram transfer sheet makes it possible to form, by a thermal head, a hologram layer 2 (composed of the hologram formation layer 13 and the light reflection layer 14) having an arbitrary shape such as a letter pattern 'A.O' on a transfer-applied body such as a card. Accordingly, even if falsification of an ID card or the like is attempted by peeling away this formed hologram layer 2 and by using an existing transparent-type hologram sheet, it is difficult to form again on the transfer-applied body, the above-mentioned hologram layer 2 having its own previously formed shape, and therefore an effect of preventing reliably the above-mentioned falsification is obtained. |
