A pants-type disposable diaper has an outer covering sheet formed of a nonwoven fabric. An absorbent body is attached on the outer covering sheet to absorb excrement from the wearer. Sheet members are bonded, (also called “end sheets” or “end holding sheets”) on the front and back, each end portion of the absorbent body being positioned and fixed between the sheet member and the outer covering sheet. The sheet member may be a laminated sheet of plastic film and nonwoven fabric, stretching of the sheet member is suppressed and it is possible to easily bring the absorbent body in close contact with the crotch region of the wearer when putting the disposable diaper on the wearer. The sheet member may also be formed of nonwoven fabric, a fiber orientation of nonwoven fabric on the sheet member then being orthogonal to the edges of end portions of the outer covering sheet in the longitudinal direction, to suppress longitudinal stretching of the sheet member.
