Absorbent article with surface structure

An absorbent article comprising:

• a surface structure located on a liquid-receiving side;
• a back sheet;
• and an absorbent core sandwiched between the surface structure and the back sheet, the surface structure including a liquid-permeable first surface sheet, a liquid-permeable second surface sheet underlying the first surface sheet, and a liquid-permeable support sheet located between the second surface sheet and the absorbent core,
• wherein, in an 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 has inner ridges each confined in a corresponding ridge of the first surface sheet, the support sheet is bonded to the recesses of the first and second surface sheets, and
• wherein elastic members extending in the longitudinal direction are attached to crests of the inner ridges of the second surface sheet to give an elastically shrinking function in the longitudinal direction so that the surface structure is formed into a curved shape.
