An absorbent article having a thickness direction, a widthwise direction and a lengthwise direction which are perpendicular to one another, and having an absorbent body exhibiting liquid absorbency, a top sheet for covering the absorbent body from the skin side in the thickness direction, and a back sheet for covering the absorbent body from the non-skin side in the thickness direction, wherein: the absorbent body has a folding guide line that guides in a manner such that folding occurs, projects toward the skin-side in the thickness direction, and is oriented in the lengthwise direction; guided-folding regions having a width no greater than the thickness of the absorbent body are formed on both sides of the folding guide line in the widthwise direction; the absorbent body and the top sheet are joined to one another by a linear compressed section oriented in the lengthwise direction; the back sheet has an adhesive section, which is a region coated with adhesive on the non-skin side in the thickness direction; and the guided-folding regions and the linear compressed section are not formed in a region overlapping the adhesive section in at least the center section in the lengthwise direction.
