1. An absorbent article comprising a topsheet having liquid permeability, a backsheet having liquid impermeability, an absorber provided between the topsheet and the backsheet, and a pair of leakage-preventing units provided on both longitudinal sides of the absorbent article with, a leakage-preventing unit comprising elastic members arranged along the longitudinal direction of the absorbent article, and sheets arranged along the longitudinal direction, which wrap the elastic members and have at least a part fixed to the topsheet, wherein
the leakage-preventing unit comprises: a central region in the longitudinal direction; and a pair of end unit regions positioned outside the central region in the longitudinal direction, the elastic members comprise: a fixed unit fixed to the sheets so that the elastic members extend in the longitudinal direction in at least the boundary between the central region and the end unit regions; and free ends positioned outside the fixed unit in the longitudinal direction, the free ends not being fixed to the sheets, the end unit regions comprise: a plurality of joint processing units in each of which a joint process for joining the portions where the sheets face each other is performed; and a non-joint processing unit in which the joint process is not performed, and the free ends are arranged in the non-joint processing unit so that the free ends are disposed between the joint processing units in a width direction of the absorbent article, and wherein the plurality of joint processing units are provided at a predetermined interval on a plurality of first lines along a predetermined direction, and at the same time, are provided at a predetermined interval on a plurality of second lines along a direction perpendicular to the predetermined direction, the first lines and the second lines intersect each other, and the joint processing units are provided at intersections of the first line and the second lines. |
