Disposable diaper capable of being put on either from the front or the back of a wearer

摘要

A disposable diaper capable of being put on from either the front or the back of a wearer is disclosed. The longitudinal end section having the fastening tapes has a waist elastic member and an extensible side part. The absorbent member is disposed such that its longitudinal end in the section having the fastening tapes is nearer to the waist portion of that section than the centerline parallel to the diaper width direction and dividing each of the extensible side parts into equal halves. Two portions on opposite sides of the centerline dividing the length of the diaper in equal halves have a saturated absorption capacity ratio of 45/55 to 55/45. The natural length of the waist elastic member in the state removed from the diaper is 60 to 80% of the length of the waist elastic member as provided in the diaper.
