Abstract
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.
