PROBLEM TO BE SOLVED: To display an image that has difficulty in alteration and has a particular visual effect, and to facilitate the determination of authentic or not.SOLUTION: An image presenting body is transferred from a backing to a base material of a personal authentication medium to display the image including personal information, and includes: an underlayer that is supported on a support so as to be peelable and has light transmissibility; and an image presenting layer transferred on the underlayer by a thermal transfer using a thermal head, containing a hologram and/or diffraction grating. The image presenting layer has two kinds of areas of a first area and a second area. The first area and the second area differ from each other in a radiation range of diffracted light under specific lighting conditions. The radiation range of diffracted light from the first area is larger than that from the second area, and the radiation range of diffracted light from the second area is included in that from the first area. The hologram and/or diffraction grating in the first area and the second area is arranged with the image on confidential information including the personal information. |
