PURPOSE:To obtain a hologram which is easy to handle and has high value as an image by fixing a light reflective member integrally to the deep side of a hologram grating. CONSTITUTION:A colored printing part 105 subjected to printing of, for example, blue, red, yellow, etc., is formed as the light reflective member on a supporting member 103 such as paper. The colored part functions as a colored background if the reflectivity as the spectral luminous efficiency thereof is >=1%. The hologram grating 101 formed on a transparent substrate is stuck by a transparent adhesive agent 104 onto this printing part 105. A luminous flux 2 of a white light source 1 is reflected and diffracted by the grating 101 and a three- dimensional image 6 superposed with the colored part 105 is observed by an observer in this constitution. The hologram is, therefore, integrated with the background. The hologram which is easier to handle and is capable of displaying the excellent image by the background is thus obtd.
