- the distance A1 may be longer than the distance B1 at the central portion of the main body portion 10 in the longitudinal direction X (A1> B1). That is, the absorber 13 may be arranged in the main body portion 10 so as to be offset from the tail side B.
- the distance A6 from the outer end of the third joint portion 20Z to the inner end of the first upright portion 20Y may be shorter than the distance B2 in the width direction Y of the main body portion 10. (B2> A6).
- the third joint portion 20Z may be continuous with the first joint portion 20X. In this case, the distance A6 is 0.
- FIG. 5 is an explanatory diagram illustrating the effect of the absorbent article 1, and is a schematic cross-sectional view of the central axis CL2 when the absorbent article 1 is attached to the pet P.
- the urinary meatus UM of the pet P to which the absorbent article 1 is attached is located at a position overlapping with, for example, the absorber 13. Pet P is excreted toward the head side A.
- a space surrounded by the first standing portion 20Y and the main body portion 10 is formed to block the urine U.
- the urine U blocked by the space surrounded by the first standing portion 20Y and the main body portion 10 passes over the absorber 13 in the process of returning to the rear (buttock side B), and thus effectively becomes the absorber 13. Be absorbed. Even if a small amount of urine U that is not absorbed by the absorber 13 exceeds the absorber 13, it is blocked by the second standing portion 30Y.
- the relational expression (A1 + A2)> (B1 + B2) is established, so that a space relatively larger is formed on the head side A than the absorber 13 and on the buttock side B, and the excreted urine U is collected. It can be widely received and blocked. Further, the urine U can be held in the space surrounded by the first standing portion 20Y and the main body portion 10 even for a short time until the urine U is absorbed by the absorber 13. Therefore, even if urine U is vigorously excreted, urine leakage from the head side A can be suppressed. In addition, urine U can be effectively guided to the absorber 13 and absorbed.
- FIG. 6 is a back view of the absorbent article 1.
- the absorbent article 1 has a locking portion 40 on one end side in the longitudinal direction of the main body portion 10.

- the locking portion 40 when the locking portion 40 is provided so as to be offset to the tail side B, a part of the tail side B of the locking portion 40 overlaps with the second leakage suppressing portion 30 in a plane, and the rest is the second leakage suppressing. It does not overlap with the portion 30 in a plane. Due to such a difference in the configuration in the thickness direction, a difference in rigidity occurs in the region where the locking portion 40 is provided.
- the region where the locking portion 40 and the first leak suppressing portion 20 or the second leak suppressing portion 30 overlap has a relatively high rigidity as the other non-overlapping regions.
- Such a region with high rigidity corresponds to the "high rigidity region" in the present invention.

- the locking portion 40 has a high-rigidity region, the high-rigidity region is less likely to be deformed than the region with relatively low rigidity (low-rigidity region), and the absorbent article 1 is misaligned or has a high-rigidity region. It is possible to suppress the turning of the edge around the.
- the high rigidity region may be formed by changing the configuration itself of the locking portion 40. That is, the locking portion may have a portion having a relatively different rigidity instead of being uniformly formed.
- FIGS. 7 to 9 are explanatory views showing a modified example of the locking portion.
- the portion having relatively high rigidity is referred to as a high rigidity portion.
