摘要：
The top sheet for an absorbent article has a plurality of fused compressed sections, wherein the fused compressed sections are located on the lowermost side in the thickness direction of the top sheet, and the back side of the top sheet has recesses or low density regions having the lowest density within the top sheet, surrounding the fused compressed sections. The top sheet for an absorbent article having a plurality of fused compressed sections can be produced by a process wherein a top sheet is situated between a member with multiple protrusions and a member with multiple recesses that engage with the multiple protrusions, and the protrusions are pressed into the recesses.
