Abstract

The invention relates to an identification document, such as a passport or the like, which consists of a plurality of sheets bound into a book at a seam. At least one of the sheets forms a data sheet provided with information and consisting at least of two layers, at least one of the layers being transparent. The format of the layers is selected so that they protrude beyond the area of the seam thereby ensuring a connection of the data sheet with the other sheets of the identification document in the area of the seam. The layers are connected into an inseparable laminate in the area of the information but do not stick together in the area of the seam.
