Title: Absorbent article having a top sheet with a lower apparent density region

Abstract: An absorbent article includes liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber sandwiched between the top sheet and back sheet, wherein the top sheet is composed of a nonwoven fabric, and the region of the top sheet that contacts the site of discharge is the low density section of the nonwoven fabric with a lower apparent density than the other regions of the top sheet.
