This invention provides a latent image pattern formed body that allows to observe a latent image having excellent visibility and authenticity discrimination and design properties than those of related arts when observed from the oblique direction. The latent image pattern formed body includes, in at least part of one surface of a substrate, a latent image region, an outline region arranged on an outline of at least part of the latent image region, and a background region arranged on a background of the latent image region and the outline region. In the latent image region, a plurality of first elements having a concave or convex shape are arranged at a first pitch in a first direction. In the background region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region. In the outline region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region or background region adjacent to the outline region. In the latent image region, the background region, and the outline region, a plurality of second elements having a color different from that of the substrate are arranged at a second pitch in a second direction. |
