Abstract
In a hook-and-loop fastener, the female member includes a plurality of lines of fiber dense portions in which the fibrous material has a high basis weight, a plurality of lines of fiber sparse portions provided between the plurality of lines of fiber dense portions, the fibrous material in the fiber sparse portions having a basis weight lower than that in the fiber dense portions, and pressed portions intersecting the plurality of lines of fiber dense portions and the plurality of lines of fiber sparse portions. Further, since the rib portions are pressed by the pressed portions obtained by the embossing process, the rib portions change shape from lines where the rib portions intersect the pressed portions, and curve toward the peeling direction shown by arrow a to be a convex shape.
