  • the sexual article 1 can be brought into close contact with the body.
  • the contraction force is larger than that of the first rear elastic member 71 on the back side, so that the front waistline region S1 is reduced. It is possible to suppress the front exterior body 50A from being shifted from one side.
  • the contraction force of the elastic member can be measured, for example, by the following method.
  • the length H0 of the elastic member in the width direction W of the effective length portion of the elastic member in a state where the absorbent article 1 is extended in the front-rear direction L to the extent that the wrinkles generated in the absorbent article 1 cannot be visually recognized is measured.

  • the post-continuous shrinkage region RCR may be arranged in a region that does not overlap with the absorbent core 20 in the thickness direction T. Thereby, it is possible to suppress a reduction in the contraction force due to the rear continuous contraction region RCR due to the rigidity of the absorbent core 20. Thereby, by making the absorbent article 1 more closely adhere to the body on the back side, it is possible to suppress not only the rear waist region S2 but also the front exterior body 50A from slipping off from the front waist region S1.
  • the rear contraction region RR is a region contracted by the second rear elastic members 721 to 724, and is a region where the second rear elastic members 721 to 724 are arranged.

  • the outer edge of the front exterior body 50A in the front-rear direction L is the outer edge of the rear exterior body 50B in the front-rear direction L (that is, the waist opening of the rear exterior body 50B). Rather, it may be closer to the center O of the absorbent main body 10 in the front-rear direction. That is, the absorbent main body 10 may be shifted to the front exterior body 50A side. In this case, in the front waistline region S1, the distance from the outer edge of the absorbent main body 10 in the front-rear direction L to the waist opening becomes shorter. Therefore, when the front exterior body 50A is bent, the distance is further shortened, and excrement easily leaks from the waist opening of the front exterior body.
  • the central contraction region CER in the front waistline region S1, it becomes difficult for the front exterior body 50A to buckle, and it is possible to reduce leakage of excrement from the waist opening. Note that, in another embodiment, the same effect can be obtained even when the central contraction region CER exists in the rear waistline region S2.
  • the outer edge of the front exterior body 50A in the front-rear direction L is the outer edge of the rear exterior body 50B in the front-rear direction L (that is, the rear exterior body).
  • the waist opening of 50B may be farther to the center of the absorbent body 10 in the front-rear direction. That is, the absorbent main body 10 may be shifted toward the rear exterior body 50B. Accordingly, in the front waistline region S1, the distance from the outer edge in the front-rear direction of the absorbent main body 10 to the waist opening is increased. By increasing the distance, the area that the front exterior body 50A can yield is increased.
  • the front exterior body 50A becomes less likely to buckle, and the area of the front exterior body 50A can be reduced. Note that, in another embodiment, the same effect can be obtained even when the central contraction region CER exists in the rear waistline region S2.
  • the center O of the absorbent main body 10 in the front-rear direction is a midpoint when the absorbent main body 10 is bisected in the front-rear direction L.
  • the waist region having the central region CR having the first low contraction region LER1 and the central contraction region CER is the front waist region S1.
  • the wearer's stomach generally protrudes above the navel, and retracts in the lower abdomen below the navel (particularly, the constriction of the lower abdomen). Therefore, the length of the waist around the stomach decreases from the waist opening arranged above the navel to the crotch side, so that the front exterior body 50A arranged on the belly side is the rear exterior body arranged on the back side. It is easier to give than 50B. Therefore, since the waistline region having the central region CR is the front waistline region, the front exterior body 50A having the central contraction region CER is arranged on the ventral side. Can be reduced.
  • the waist region having the central region CR may be the rear waist region S2.
  • the rear exterior body 50B may be caught by the protrusion of the buttocks by lifting the absorbent article 1, and the rear exterior body 50B may be warped.
  • the rigidity of the central region CR is increased by the presence of the central contraction region CER, even if the rear exterior body 50B is caught by the protrusion of the buttocks, the rear exterior body 50B can be made difficult to bend.
  • a part of the central contraction region CER is arranged outside the absorbent main body 10 in the front-rear direction L, but is not limited thereto.
