Abstract

An object of the invention is to improve the diffusibility of body fluid such that the body fluid can be quickly absorbed. The sanitary napkinrepresented by FIG.includes an absorbing bodywith a highly water-absorbent polymerinterposed between an upper layer sheetdisposed on the skin side and a lower layer sheetdisposed on the non-skin side. The upper layer sheethas a plurality of first protrusionsforming first space partsthat are to be filled with the highly water-absorbent polymer and that expand to the skin side, and a plurality of second protrusionsforming second space parts, each of which having a smaller volume than each of the first space part, that are to be filled with the highly water-absorbent polymer and that expand to the skin side. The weight per unit area of the highly water-absorbent polymerfilled into the second space partsis made smaller than the weight per unit area of the highly water-absorbent polymerfilled into the first space parts
