ABSTRACT:
A hologram element includes an optically transparent base plate having first and second opposite surfaces. A film of a diffraction grating is provided on the first surface of the base plate. A nonreflective member is provided on the second surface of the base plate via a dipping process. The nonreflective member includes one of a film including SiO.sub.2 particles and a film of MgF.sub.2. It is preferable that the SiO.sub.2 particles have diameters of 10-150 nm. The diffraction grating film includes, for example, one of a gelatine film, a photopolymer film, and a photoresist film. The base plate includes, for example, a flexible resin film. It is preferable that the flexible resin film is made of a material selected from the group consisting of amorphous polyolefine, polycarbonate (PC), polymethyl methacrylate (PMMA), and perfluoroalkoxypolyethylene (PFA).
