A disposable diaper capable of preventing and end edge part from getting stuffy by preventing open holes formed when it is worn from being clogged. A belt-like elastic member 7 for the surrounding of a waist fitted to the end edge part 1c of a rear waist peripheral area 22 has both-side edge 7a and upper / lower end edges 7b and 7c, plural slits 8 extending in a vertical direction passing through the diaper in its thickness direction are arranged at intervals of a given size in the waist peripheral direction between the edges 7a of the member 7 and are arranged at intervals of a given size in the vertical direction between the neighborhood of the edge 7b of the member 7 and the neighborhood of the edge 7c.

Description

technical field [0001] The present invention relates to a disposable diaper for absorbing and retaining excrement. Background technique [0002] In Japanese Patent Application Publication No. 6-9620, an open type disposable diaper is proposed. In this diaper, a liquid-absorbent core is sandwiched between a liquid-permeable surface layer and a liquid-impermeable inner layer. Several slits extending along the longitudinal direction are formed on the fins protruding outward from the two side edges. The slits are formed on the flaps extending toward the front and rear body regions, arranged longitudinally at a predetermined size, and along the waistline at a predetermined size. When the flap is pulled toward the waistline, the slit of the diaper expands toward the waistline, forming a plurality of openings in the flap. When the diaper is in use, the moisture inside the diaper can be dissipated from the opening to the outside, which can prevent the diaper from being stuffy. ...
