An authentication hologram uses a Lippmann hologram that enables a 3D object image having a vertical and horizontal field of vision as well as planar with added information viewable at a specific angle alone. In that authentication hologram, a hologram for reconstructing a 3D object image and a hologram mirror pattern that is formed at a pattern portion corresponding to the added information and has planar interference fringes placed one upon another and parallel at a constant spacing are recorded in a superposing fashion.
