The booklet (1) comprises a number of sheets (31 between a cover (23), and each sheet has a front side and a rear side. At least one data page (2, 24 -27, 37) is provided that is joined to the cover (23) in a fixed manner. The data page (2, 24-27, 37) comprises a flexible layer (3-7, 38) and this flexible layer (3-7, 38) projects with an area (3b, 4b, 5b, 6b, 7b) out of a data carrier (9, II, 13, 14, I8, 41). On this area (3b, 4b, 5b, 6b, 7b), the data page (2, 24 -27,

37) is joined to the cover (23) and to the remaining sheets (31). The flexible layer (3-7) is flatly joined t o at least one other layer (9, 11a, 13, 14a, 18, 41),

for example, by welding or bonding and is thus inseparably bound without a mechanical joining part.
