ABSTRACT:
Disclosed is an absorbent article including a liquid absorbent layer for absorption and retention of liquid and a liquid passage layer located on a liquid-receiving side of the liquid absorbent layer. The liquid passage layer includes a first passage layer and a second passage layer disposed between the first passage layer and the liquid absorbent layer. The first passage layer and the second passage layer are resin films formed with a plurality of liquid passage apertures. The individual liquid passage apertures are defined by a peripheral wall projecting toward the liquid absorbent layer to provide the first passage layer and the second passage layer with thicknesses greater than a thickness of the resin film itself. Under a load in a thickness direction, the second passage layer has a greater compressibility than the first passage layer.
