Abstract
Disclosed is an absorbent assembly including a main absorbent part (21) composed of a highly absorbent polymer and absorbent fibers, a crepe paper sheet (22) wrapped around the main absorbent part, and a second sheet (25) arranged on a portion of the crepe paper sheet (22) wrapped around one of the major surfaces of the main absorbent part (21). The major surfaces of the main absorbent part (21) are hot-melt bonded to the crepe paper sheet (22). The weight ratio of the highly absorbent polymer to the total weight of the highly absorbent polymer and absorbent fibers of the main absorbent part (21) is set to 40 wt % or higher. The absorbent assembly is pressurized to reduce its thickness. The second sheet (25) contains polyethylene terephthalate, exhibiting high cushioning performance, as its component material. The liquid is diffused and the area over which the liquid is intruded into the main absorbent part is enlarged to prevent the absorptive power of the absorbent assembly from being lowered.
