PANTS TYPE DISPOSABLE DIAPER

摘要

A pants type disposable diaper in which side seal sections simultaneously achieve both sufficient seal strength and ease of separation. In the pants type disposable diaper, a belly-side exterior sheet (12F) and a rear-side exterior sheet (12B) are separated from each other without being connected to each other on the crotch side. The exterior sheets (12F, 12B) have a waist-side folded back portion (21) and a crotch-side folded back portion (22). The crotch-side edge of the waist-side folded back portion (21) and the waist-side edge of the crotch-side folded back portion (22) agree with each other. The number of plies in that portion of a sheet-like air permeable material (12) which is at a waist-side end and the number of plies in that portion of the sheet-like air permeable material (12) which is at a crotch-side end are the same. Further, the number of plies in that portion of the sheet-like air permeable material (12) which is at an intermediate section between the waist-side end and the crotch-side end is the same as or less than the number of plies in those portions of the sheet-like air permeable material (12) which are at the waist-side end and the crotch-side end.
