Abstract: A booklet includes a sheet-like first substrate, and a sheet-like second substrate that is attached to the first substrate. The first substrate includes a light-transmitting region, and an optical functional unit is provided to the light-transmitting region. A latent image is provided to a surface of the second substrate that is opposite to the first substrate at a position corresponding to the optical functional unit. The latent image manifests when the optical functional unit operates by overlapping the first substrate with the second substrate.
