Abstract
A passport includes a data sheet of an individual and a plurality of visa sheets combined with the data sheet and bound by a thread to form a thread binding along a central folding line. A surface of an individual's data printing page of the data sheet is laminated with a protective film composed of a see-through synthetic resin film. An anti-counterfeit structure of the passport is characterized in that the protective film is laminated over a gutter portion of the data sheet including the central folding line, and the thread binding is formed through the laminated area of the gutter portion.
