Abstract (en)
A nonwoven fabric provided with unevenness and openings, regulated so that without extremely increasing of fiber density at protrudent portions, depressed portions, etc., only part of the periphery of each open area is densified. One side edge portion (14,16) of each open area (3a,3b) is formed by shifting of fiber web (100) toward the low position of wire (302) with a gradient extending in the direction of width (WD). Nearly none of fiber web (100) is shifted to the side edge portion opposite to the one side edge portion (14,16) of open area (3a,3b), namely, other side edge portion (15,17).
