The invention provides 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 1 of the invention has a mutually perpendicular MD direction, CD direction 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 2 and recesses 13a 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 3 formed across the entire side, the heights 2 being composed of height tips 21 located at the tips 2a of the heights 2 and neck sections 22 connecting the height tips 21 with the back side section 3, the cross-sectional widths of the neck sections 22 being narrower than the height tips 21 in a cross-section of the heights 2 in the CD direction, and having spaces between the recesses 13a formed by the two neck sections 22 supporting each of the adjacent height tips 21, and the back side section 3.
