Abstract: A personal identification medium is provided that includes a decorative layer provided with an antenna, and a laser marking layer in which a personal information marking portion is marked on the decorative layer, where the antenna includes a non-decorative portion and a decorative portion connected to the non-decorative portion, and the personal information marking portion formed on the laser marking layer overlaps at least a portion of the decorative portion formed on the decorative layer.

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.

Abstract: A transponder includes an inlet including an antenna sheet, which includes an antenna coil on a flexible first base material, and an IC module connected to the antenna coil, and a second base material, which has an opening for exposing at least a part of the IC module and is bonded to the inlet; a sealing material having electrical insulation is provided between the IC module and an inside face of the opening.

Abstract: A contactless communication medium which can prevent invasion of static electricity and has an outer surface which can satisfy requirements on the flatness thereof. The contactless communication medium has a sealing member including an insulating layer and a conductive layer provided in a stacked manner and having a shape covering an IC module is located such that the insulating layer is on the IC module side. Owing to this, static electricity coming from outside is diffused by the conductive layer and blocked by the insulating layer. Thus, adverse influence of the static electricity on the IC module is prevented. The contactless communication medium can also satisfy the requirements on the flatness of an outer surface thereof.

Abstract: An antenna sheet is provided with a flexible substrate, and an antenna coil, which is connected to a terminal section of an external IC module having an IC chip and is arranged on the substrate. On the substrate, a storing section that stores at least a part of the IC module is formed.

A contactless communication medium is provided, in which a sealing member including an insulating layer and a conductive layer provided in a stacked manner and having a shape covering an IC module is located such that the insulating layer is on the IC module side. Owing to this, static electricity coming from outside is diffused by the conductive layer and blocked by the insulating layer. Thus, adverse influence of the static electricity on the IC module is prevented with certainty. The contactless communication medium can also satisfy the requirements on the flatness of an outer surface thereof.
