Abstract
A comfortably wearable development type paper diaper comprises a back sheet, a first absorbent, a second absorbent and a liquid-permeable top sheet in the recited order. The first absorbent extends, when worn, from the back side through the crotch to the abdomen side of the user. The second absorbent extends, when worn, from the back side to the crotch of the user. A leakage preventing sheet allowing no liquid permeation is interposed between the first absorbent and the second absorbent. The second absorbent leaves the first absorbent from the crotch to the back side thereby to form a pocket PO for holding the excrement between the first absorbent and the second absorbent. The leakage preventing sheet is arranged to contact in the pocket PO with the second absorbent. The top sheet is so conformed to the shape of the pocket PO as to cover the leakage preventing sheet.
