An attachable-type disposable wearing article including a waist stretchable region having waist elastic members and a first and second sheet layers sandwiching the same, and stretchable in the width direction and contracting in the width direction, the wearing article further including joined zones of the first sheet layer and the second sheet layer and unjoined zones of the first sheet layer and the second sheet layer provided continuously from forward of the waist stretchable region to backward thereof, with the joined zones and the unjoined zones arranged alternately and repeatedly in the width direction, wherein at least one of the unjoined zones has opposed lateral edges with oblique portions extending at an inclination angle of 5 to 45 degrees with respect to the front-back direction.

Attachable-type disposable wearing article

A configuration in which an upper auxiliary layer of an absorber includes a super absorbent nonwoven fabric having a surface exposed on an uppermost surface of the absorber and having a Klemm water absorptiveness of 100 mm or more, first super absorbent polymer particles adjacent to a back surface of the super absorbent nonwoven fabric. The main absorption layer of the absorber is a cell absorbing sheet including second super absorbent polymer particles contained in the cells arranged at intervals. A convex bulging upward is formed at each cell in an upper sheet. The first super absorbent polymer particles are fixed to the upper surface of the upper sheet. An adhesion amount of the first super absorbent polymer particles on the upper surface of the upper sheet increases from the top of a convex toward the bottom of a valley between a convex and a convex adjacent each other.

Absorbent article

An absorber, a liquid impervious sheet covering a back surface side of the absorber and having air permeability, and a cover nonwoven fabric covering a back surface side of the liquid impervious sheet are provided. The cover nonwoven fabric has a large number of holes penetrating the front surface and back surface at intervals in a region overlapping with the liquid impervious sheet. Edge portions of the holes bend-up toward a front surface side. In a region having the holes in the cover nonwoven fabric, rows of the holes, which are aligned in the front-back direction at intervals in the front-back direction narrower than the dimension in the front-back direction of each of the holes, are repeatedly formed at predetermined intervals in the width direction, and the interval of the adjacent two holes in the width direction is wider than the dimension in the front back-direction of the hole.
