Abstract
The present invention aims to provide a liquid-pervious sheet suitable to be used as a liquid-pervious topsheet of a bodily fluid-absorbent wearing article. One surfaceof both surfacesof a liquid-pervious sheetis formed with crestsand troughsextending in parallel to one another in a longitudinal direction A and alternate in a transverse direction B. The one surfaceis additionally formed at least in the respective crestswith a series of compressed debosses. In the respective compressed debosses, thermoplastic synthetic fibers forming the liquid-pervious sheetmore densely gather together than in zones surrounding the respective compressed debossesand thereby maintain initial fiber formation of the individual thermoplastic synthetic fibers.
