Provided is a disposable diaper having a fluid permeable first surface layer and a fluid permeable second surface layer, which are used in a bodily fluid absorption structure.The absorption structure (4) of a disposable diaper (1) is disposed between a fluid permeable, human body-side liner (2) and a fluid impermeable outer cover (3). The human body-side liner (2) is formed by: a first surface layer (2a) which has a contact surface coming into contact with the skin and which extends from the peripheral edge (4a) of the absorption structure (4) and a second surface layer (2b) which is located on the inside of the peripheral edge (4a) and which is disposed between the first surface layer (2a) and the absorption structure (4). Ridges (34) extending in the longitudinal direction (A) so as to be substantially parallel to each other are formed on the contact surface of the first surface layer (2a). The second surface layer (2b) is configured in such a manner that the inner region (52) thereof is bonded to the first surface layer (2a) by an adhesive agent (Ad1) and that the outer regions (53) thereof located on the outside transversely of the inner region (52) are bonded in first compressed sections (55a) to the first surface layer (2a).La présente invention concerne une couche jetable ayant une première couche de surface perméable aux fluides et une deuxième couche de surface perméable aux fluides, qui sont utilisées dans une structure dabsorption de fluide corporel.La structure dabsorption (4) dune couche jetable (1) est disposée entre un revêtement côté corps humain perméable aux fluides (2) et une couverture externe imperméable aux fluides (3). Le revêtement côté corps humain (2) est formé de : une première couche de surface (2a) qui a une surface de contact entrant en contact avec la peau et qui sétend depuis le bord périphérique (4a) de la structure dabsorption (4) et une deuxième couche de surface (2b) qui est située sur lintérieur du bord périphérique (4a) et qui
