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
