Abstract: An absorbent article includes a topsheet comprising a composite sheet. In the composite sheet, projections that protrude toward the skin of the wearer are formed by a first sheet protruding in a direction away from a second sheet at portions other than bonding portions. A plurality of first oblique bonding portion rows and a plurality of second oblique bonding portion rows are formed, and a long bonding portion elongated in a longitudinal direction is formed at each intersection of the first oblique bonding portion rows and the second oblique bonding portion rows. Laterally long projections elongated in a width direction are formed in a dispersed manner in the longitudinal direction and the width direction. Each laterally long projection is surrounded by two first oblique bonding portion rows and two second oblique bonding portion rows, and the long bonding portion is formed between adjacent laterally long projections in the width direction.

Abstract: An absorbent article including an absorbent member and a topsheet 2 on the skin facing side of the absorbent member is disclosed. The topsheet 2 includes a stack of a first sheet 20 and a second sheet 21. The topsheet 2 has a plurality of projections 23 resulting from the first sheet 20 protruding toward the skin of a wearer. The topsheet satisfies the following conditions: (1) the projections have a height of 0.5 to 10 mm; (2) the bonds 22 have a density of 10 to 30 bonds per a randomly chosen rectangular region measuring 10 mm in length and 15 mm in width in plan view; (3) the bonds in the rectangular region have a total area ratio of 12% to 35% relative to the area of the rectangular region; and (4) the topsheet has a shear strength of 21 to 70 N.
