## 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.

## Claims

### Claim 1

A personal identification medium, comprising:
a decorative layer provided with a first portion including a fine line art pattern;
a laser marking layer, in which a personal information marking portion is marked, on the decorative layer;
a colored layer provided between the decorative layer and the laser marking layer; and
a light transmissive energy resistant layer provided between the colored layer and the decorative layer,
wherein
the decorative layer is formed of a material which is same as a material used for the light transmissive energy resistant layer,
the personal information marking portion formed on the laser marking layer overlaps at least a portion of the first portion formed on the decorative layer,
the colored layer comprises a colored portion and a window portion,
the window portion is formed in an area overlapping the first portion formed on the decorative layer, and
