A nonwoven fabric that minimizes the condition of rewet-back in which fluid absorbed into an absorbent body exudes out to the front side, as well as a method for producing it. The nonwoven fabric has a mutually perpendicular machine direction (MD), cross-machine direction (CD) and thickness direction, and has in the thickness direction a front side and a back side on the side opposite it, having on the front side heights and recesses formed so as to extend in an alternating fashion parallel to each other in the MD direction, forming repeating corrugations in the CD direction, and on the back side a back side section formed across the entire side, the heights being composed of height tips located at the tips of the heights and neck sections connecting the height tips with the back side section, the cross-sectional widths of the neck sections being narrower than the height tips in a cross-section of the heights in the CD direction, and having spaces between the recesses formed by the two neck sections supporting each of the adjacent height tips, and the back side section.
