PROBLEM TO BE SOLVED: To provide a disposable diaper in which air permeability and fitting of a side panel are excellent and stretchability of the side panel is hardly damaged even when strong tensile force is applied.SOLUTION: The disposable diaper 1 includes: an absorbent body including an absorber and stretch side panels extending from both side edges of the absorbent body. The side panel 3 has a stretch part 30 where a plurality of stretch members are separately arranged between two sheets of nonwoven fabric, and has a tab 4 which has a fixing part and is provided on a distal end part of the side panel. The stretch part 30 has: a portion which is positioned in a range H1 having the tab 4 in a direction (Y direction) crossing the extending direction of the side panel and which is a high stretch stress part Ga having high stretch stress and a portion which is positioned closer to crotch part side than the high stretch stress part in the same direction (Y direction) and which is a low stretch stress part Gb having the stretch stress lower than that in the high stretch stress part Ga.COPYRIGHT: (C)2012,JPO&INPIT【課題】サイドパネルの通気性及びフィット性に優れ、強い引っ張り力が加わってもサイドパネルの伸縮性が損なわれ難い使い捨ておむつを提供すること。【解決手段】吸収体を含む吸収性本体と、該吸収性本体の両側縁から延出する伸縮性のサイドパネルを備えた使い捨ておむつ1であり、サイドパネル3は、2枚の不織布間に複数本の弾性部材が離間配置された伸縮部30を有し、先端部に、止着部を有するタブ4が設けられており、伸縮部30は、サイドパネルの延出方向と交差する方向(Y方向)におけるタブ4を有する範囲H1に位置する部分が、伸長応力が高い高伸長応力部Gaとなっており、同方向(Y方向)における高伸長応力部よりも股下部側に位置する部分が、該高伸長応力部Gaよりも伸長応力が低い低伸長応力部Gbとなっている。【選択図】図3
