Claims

1. A disposable absorbent article comprising: an outer cover; andan absorbent member attached to the skin facing side of said outer cover, said absorbent member including an absorber, whereinat least a crotch zone of said outer cover is subjected to a softening process for softening a material of said outer cover.

2. The disposable absorbent article according to claim 1, wherein a plurality of almost slit-like holes extending through said outer cover are provided in a portion of said outer cover having been subjected to the softening process.

3. The disposable absorbent article according to claim 1, wherein a portion of said outer cover subjected to the softening process is softened by application of blades of a cutter.

4. The disposable absorbent article according to claim 1, further comprising elastic members attached from along leg-side edges of said outer cover surrounding the wearer's left and right legs to said crotch zone, whereinpart of said elastic members attached to said crotch zone is cut short to be weakened.

5.
