The main purpose of the present invention is to provide a hologram structure having excellent fraud prevention properties and design properties. The present invention solves the above problem by providing a hologram structure characterized in having: a hologram layer that has a reflective hologram formation region in which there is recorded a phase-type Fourier transform hologram for converting light entering from a point light source into a desired optical image; and a vapor deposition layer formed so as to be in contact with the surface of the reflective hologram formation region of the hologram layer, the reflective hologram formation region being 5 to 50 square millimeters large, as seen in plan view, and the surface of the reflective hologram formation region having protrusions and recesses. |
