Abstract
An absorbent article has a longitudinal direction and a lateral direction perpendicular to each other, and includes a waist part along the lateral direction. The waist part includes nonwoven fabric and a plurality of stretchable members. In a state in which the waist part is extended along the lateral direction, an opening is formed in the waist part between stretchable members that are adjacent in the longitudinal direction. A high density region exists longitudinally between the opening and one of the adjacent stretchable members. An external region exists longitudinally between the high density region and another one of the adjacent stretchable members. The high density region has a predetermined lateral length. A density of fibers of the nonwoven fabric in the high density region is larger than in the external region. A part of an edge of the opening includes a portion in which fibers are not fused.
