摘要： A body fluid absorbent wearing article includes a liquid-absorbent panel 4. The panel 4 is composed of a first fibrous assembly panel 5 lying on the side of a topsheet 2 and a second fibrous assembly panel 6 underlying the first sub-panel 5. The first sub-panel 5 has a flat portion 5a, a plurality of protuberant portions 5b and a plurality of wall portions 5c. The first sub-panel 5 has a fiber density progressively increasing as the first panel 5 gets nearer to the second sub-panel 6 having a fiber density higher than that of the first panel 5. The panel 4 thus formed rapidly spreads body fluids thereover and prevent the body fluids from flowing back to a top surface of the article.
