    • There is disclosed an absorbent article including: a surface structure having a liquid-permeable surface sheet located on a liquid-receiving side; a back sheet; and an absorbent core sandwiched between the surface structure and the back sheet. In an area including at least a centerline extending in a longitudinal direction of the absorbent article, the surface sheet is corrugated to form recesses and ridges extending in the longitudinal direction and alternating with each other in a transverse direction perpendicular to the longitudinal direction. The ridges are given an elastically shrinking function in the longitudinal direction at least at their crests or vicinities thereof so that the surface structure is formed into a curved shape. The surface structure thus curved can fit the shape of a crotch. Therefore, the liquid is hard to flow in the transverse direction to prevent the leakage.

    • An absorbent article comprises: a surface structure (4) located on a liquid-receiving side; a back sheet (3); and an absorbent core (2) sandwiched between the surface structure and the back sheet. The surface structure includes a liquid-permeable first surface sheet (5), a liquid-permeable second surface sheet (15) underlying the first surface sheet, and a liquid-permeable support sheet (6) located between the second surface sheet (15) and the absorbent core (2). In area including at least a centerline extending in a longitudinal direction of the absorbent article, the first and second surface sheets are corrugated to form recesses and ridges extending in the longitudinal direction and alternating with each other in a transverse direction perpendicular to the longitudinal direction, respectively, so that the second surface sheet (15) has inner ridges each confined in a corresponding ridge of the first surface sheet (5). The support sheet (6) is bonded to the recesses of the first and second surface sheets, and elastic members (10) extending in the longitudinal direction are attached to the crests of the inner ridges of the second surface sheet (15) to give an elastically shrinking function in the longitudinal direction so that the surface structure is formed into a curved shape.
    • 吸收性物品包括:位于液体接收侧的表面结构(4); 背板(3); 和夹在表面结构和背板之间的吸收芯(2)。 表面结构包括透液性第一表面片(5),第一表面片下方的透液性第二表面片(15)和位于第二表面片(15)之间的透液性支撑片(6) 和吸收芯(2)。 在包括至少沿着吸收性物品的长度方向延伸的中心线的区域中,第一和第二表面片是波纹状的,以形成在纵向方向上延伸并且在垂直于纵向方向的横向上彼此交替的凹槽和脊部, 使得第二表面片(15)具有限定在第一表面片(5)的相应脊中的内脊。 支撑片(6)接合到第一和第二表面片的凹部,并且沿纵向方向延伸的弹性构件(10)附接到第二表面片(15)的内脊的顶部,以得到 在纵向方向上具有弹性收缩功能,使得表面结构形成为弯曲形状。
