Since the post-processing member and the main body adhesive part are separated from the length of the hook member tip protruding toward the non-skin surface side with respect to the main body adhesive part, when the hook member falls down, the hook member and main body adhesive part It is difficult for the department to contact. Therefore, it is possible to prevent a problem such as unintentionally joining the main body adhesive portion and the post-processing member in the state before the disposal.

It is easy to secure the area for disposing the main body adhesive portion on the outer side in the width direction of the post-processing member. Further, since the post-processing member is narrow, the width of the region where the surface sheet and the hook member are in contact is small, and the hook member once joined to the surface sheet can be easily peeled from the surface sheet. Therefore, the body portion can be re-rolled after being rolled in an unintended manner.
  • the post-processing member is narrow, it is easy to fold compactly when the main body is folded in the width direction with the outer edge of the post-processing member as a base point at the time of disposal. Therefore, the absorbent article can be discarded in a compactly folded state.
  • the post-treatment member may be arranged so as to straddle the center of the main body in the width direction.

  • the pair of post-processing members sandwiching the center of the main body in the width direction can maintain the rolled state of the entire main body in the width direction. Since the length in the width direction that can be joined by the post-processing member can be secured, it is particularly suitable for the main body portion having a long length in the width direction.

Therefore, when the post-treatment member is joined to the surface sheet at the time of disposal, the rolled state can be maintained, and the absorbent article can be disposed of cleanly by the post-treatment member.
  • the post-treatment member may be arranged without straddling at least one of the first folding line and the second folding line.
  • the main body has a crease formed by a fold line. In the state where the main body is rounded with the skin side inside, the front side region and the back side region with the fold line as a boundary are deformed to the skin surface side (inside) with the fold line as the base point. If the sheet is deformed inward with the folding line as a boundary, the post-processing member and the surface sheet may separate from each other, and the hook member and the surface sheet may be difficult to bond, or the hook member once bonded may come off. By not straddling the fold line, it is possible to prevent the joining state of the hook members from being unintentionally disengaged due to a folding tendency.
  • the hook member may be thicker than the surface sheet. According to this aspect, when the hook member is pressed toward the surface sheet, the tip of the hook member penetrates the surface sheet, and the hook member is easily caught on the surface sheet. As a result, the hook member is joined to the surface sheet, the rolled state is maintained by the hook member, and the post-processing member facilitates clean disposal.
  • the thickness of the hook member may be thinner than the thickness of the topsheet.
