Abstract:
1. A body fluid absorbing article comprising: an absorbent sandwiched between a body fluid permeable surface member and a body fluid impermeable back member, wherein said absorbent includes an upper layer and a lower layer disposed between said body fluid permeable surface member and said body fluid impermeable back member; wherein said lower layer has a higher density than that of said upper layer by forming indented recesses in the lower layer of said absorbent that underlies said upper layer into a continuous honeycomb shape; wherein said indented recesses are formed in linear portions having an angle of 45 degrees or less between an inclination direction of said indented recesses and a longitudinal direction of the article; wherein said indented recesses have an emboss percentage of 30 to 55%, as determined by the ratio of the thicknesses before and after an embossing treatment; wherein said lower layer extends beyond an outer edge of said upper layer; and wherein said absorbent has relations of B>C>A, when said upper layer has a density A, a portion of said lower layer that underlies the upper layer has a density B, and the remaining portion of said lower layer that extends beyond the outer edge of said upper layer has a density C; wherein the density A is 20 to 50 Kg/m wherein the shortest mutual distance of said indented recesses is 3 mm or less.
