[0003]

In the above-mentioned conventional method, in addition to the two laminated sheets for recording the ID information, another member such as paper for recording the ID information is required. Was complicated. In addition, lamination of a laminate sheet is performed by forming a heat sealant layer on at least one of the two laminate sheets and performing lamination, but the sheets are bonded only around a piece of paper on which ID information is written, Therefore, there is a problem that the bonding area is small and sufficient bonding strength cannot be obtained, and forgery is possible by peeling off the sheet and replacing the paper piece sandwiched between the sheets.

In the above method, a hologram sheet or the like is attached to a card for the purpose of improving the security of the card. Although the security of the hologram sheet is improved, the ease of peeling of the laminate sheet is not improved. Still, it is not a decisive means of preventing forgery. Accordingly, an object of the present invention is to provide an ID card which is difficult or impossible to forge and which is easy to manufacture, and a method for manufacturing the same.

[0005]

The above object is achieved by the present invention described below. That is, the present invention provides that two laminated sheets, at least one of which is substantially transparent, are laminated with a heat sealant, and that the ID information is printed and formed on the laminated surface of at least one of the sheets. An ID card and a method of manufacturing the same are provided.

According to the present invention, ID information is printed and formed on at least one surface of two laminated sheets.
Since two sheets are laminated with the information inside,
A conventional paper piece for recording ID information is not required. Further, in the present invention, since no paper piece is used, the bonding area between the two sheets is significantly larger than that of the conventional ID card, and it is difficult to peel them off.

Further, according to the present invention, the ID information is integrated with the heat sealing agent layer between the two laminate sheets, and it is impossible to change the ID information.
By providing a substantially transparent hologram layer or diffraction grating layer (hereinafter simply referred to as a hologram layer) on at least one of the two sheets, the security and design of the obtained ID card are further improved. This hologram layer may be formed on the entire laminate sheet,
It may be partly formed in a pattern.
