PROBLEM TO BE SOLVED: To provide a disposable diaper in which the absorber is improved in fitting properties with the body of a wearer and also the surface sheet is improved in dry feeling.SOLUTION: An absorber 4 has an absorptive core 40 including absorbing polymer. A non-fiber-stacked part 42 elongated in a longitudinal direction X is formed in the absorptive core 40. A surface sheet 2 comprises a fiber sheet having two layers. The fineness of the fiber at the side of a skin-facing surface of the surface sheet is lower than the fineness of the fiber at the side of a non-skin-facing surface. The thickness of the surface sheet 2 at a portion located on the absorptive core 40 is larger than the thickness at a portion located at the non-fiber-stacked part 42. A part of the portion in a thickness direction of the portion located at the non-fiber-stacked part 42 of the surface sheet 2 exists in the non-fiber-stacked part 42.SELECTED DRAWING: Figure 3 【課題】着用者の身体と吸収体とのフィット性を向上させつつ、表面シートのドライ感が向上した使い捨ておむつを提供すること。【解決手段】吸収体４は、吸収ポリマーを含む吸収性コア４０を有し、吸収性コア４０に、縦方向Ｘに延びる非積繊部４２が形成されている。表面シート２は、２層を有する繊維シートである。表面シートは、肌対向面側の繊維の繊度が、非肌対向面側の繊維の繊度に比べて低くなっている。表面シート２は、吸収性コア４０上に位置する部位での厚みよりも、非積繊部４２に位置する部位での厚みの方が大きくなっている。表面シート２のうち非積繊部４２に位置する部位は、該部位の厚み方向の一部が非積繊部４２内に存在している。【選択図】図３
