PROBLEM TO BE SOLVED: To provide an absorbent article, even when leg perimeters of a wearer are rubbed by outlines in both sides of the absorbent article and free ends of three-dimensional gathers, being unlikely to cause skin trouble due to the rubbing.SOLUTION: Outlines in longitudinally both sides of a sanitary napkin 1 are formed into a wavy frill shape, and free ends of three-dimensional gathers BS are also formed into a wavy frill shape. The outlines in longitudinally both ends and the free ends of the three-dimensional gathers BS of the sanitary napkin 1 are formed into the wavy frill shape respectively. The three-dimensional gather BS has at least one elastic stretchable member 8 along the longitudinal direction of the sanitary napkin 1, and the elastic stretchable member 8 is disposed not to be overlapped with the frill shape of the three-dimensional gather BS.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】吸収性物品の両側の外形線及び立体ギャザーの自由端が脚周りに擦れて摩擦による肌トラブルを生じ難くする。【解決手段】生理用ナプキン1の長手方向両側の外形線を波状を成すフリル状に形成するとともに、立体ギャザーBSの自由端を波状を成すフリル状に形成する。生理用ナプキン1の長手方向両側の外形線及び立体ギャザーBSの自由端がそれぞれ波状を成すフリル状に形成されている。前記立体ギャザーBSは、生理用ナプキン1の長手方向に沿って少なくとも1本の弾性伸縮部材8を有し、該弾性伸縮部材8は、前記立体ギャザーBSのフリル形状に重ならないように配設されている。【選択図】図1
