Absorbent article
First Claim
1. An absorbent article having a longitudinal direction and a lateral direction perpendicular to each other, the absorbent article comprising:
- a waist part along the lateral direction, the waist part including;
nonwoven fabric having fibers; and
a plurality of stretchable members that stretch and contract in the lateral direction, whereinin 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,the nonwoven fabric of the waist part includesa high density region existing longitudinally between the opening and one of the adjacent stretchable members, andan external region existing 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 the fibers of the nonwoven fabric in the high density region is higher than a density of the fibers of the nonwoven fabric in the external region, andat least a part of an edge of the opening includes a no-fused portion in which the fibers are not fused.

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.

9. An absorbent article having a longitudinal direction and a lateral direction perpendicular to each other,
the absorbent article comprising: a waist part along the lateral direction, the waist part including; nonwoven fabric; and a plurality of stretchable members that stretch and contract in the lateral direction, in a state in which the waist part is extended along the lateral direction, an opening being formed in the waist part between stretchable members that are adjacent in the longitudinal direction, at least a part of an edge of the opening including a no-fused portion in which fibers of the nonwoven fabric are not fused, at least a part of an edge of the opening including a fused portion in which the fibers are fused, a center of the opening being located longitudinally above or below a center between the adjacent stretchable members.
