Abstract:
An absorbent article using a surface sheet in which a side of the surface coming into contact with a skin is made of a non-woven fabric and a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, wherein the residence of a body fluid due to a capillary phenomenon or surface tension in an aperture wall part of the foregoing surface sheet is reduced and the body fluid is rapidly moved into a side of a hydrophilic second sheet or absorber as a lower layer, thereby not only keeping dryness and smoothness on the surface but also preventing turning back with a lapse of time. A surface sheet has a structure in which a side of the surface coming into contact with a skin is made of a non-woven fabric, a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, and a number of projecting parts and recessing parts are formed by embosses and a number of apertures are formed in the side of the surface coming into contact with a skin; and the foregoing apertures are formed in a proportion so as to have an aperture area of from 0.35 to 0.60 mm2 per aperture and an aperture ratio of from 10 to 19%, and the aperture shape is an aperture shape not having an angledly bent corner.
