The invention relates to an incontinence diaper (2) with a main part (4), which comprises a front region (12), a rear region (16), and a crotch region (20) arranged between the front region and the rear region, and with rear lateral sections (22) which are joined to the rear region (16) on both sides, which extend outwards in the transverse direction (10) of the incontinence diaper (2) over the rear lateral longitudinal edges (18) of the main part (4), and each of which has at least one closure means (28), whereas no lateral sections (22) are joined to the front region (14). Each of the rear lateral sections (22) can be placed around the body of the user in order to close the incontinence diaper (2) and can be brought into overlapping arrangement with a front region (12) exterior, to which the lateral sections can then be removably adhered via the respective closure means (28). The rear lateral sections (22) have an extension (Q) in the transverse direction (10) over the respective rear lateral longitudinal edge (18) and an elastic or elasticized region (42) which extends in the transverse direction (10) and in the longitudinal direction (8). The invention is characterized in that the rear lateral sections (22) are folded together about at least two lateral section folding axes (46, 48) running in the longitudinal direction (8) by the manufacturer, and folded together sub-regions (50, 52, 54) of the rear lateral sections (22) are defined and delimited by means of the lateral section folding axes (46, 48). An outer sub-region (54) in the transverse direction (10) is designed to be substantially unstretchable, and at least 50% of the surface of a sub-region (52) which adjoins the outer sub-region (54) inwards is unstretchable starting from the outer folding axis (48) running in the longitudinal direction.
