Abstract
The present invention provides an image-formed object having security property improved, in which, even in the case where the image-formed object comprises a plurality of optical diffraction structures, the presence of each optical diffraction structure is hardly recognized. An image-formed object comprises a background region where an optical diffraction structure for background focusing a predetermined design as a hologram image at a predetermined image-formation distance, and at least one inset region provided so as to be inset in the background region, wherein, in the inset region, an optical diffraction structure for inset focusing a hologram image of the same design and color as the hologram image of the optical diffraction structure for background is formed at an image-formation distance different from the image-formation distance of the optical diffraction structure for background.
