- the first core material covering sheet 3a and the second core material covering sheet 3b partially overlap each other so that they absorb the water absorbent fibers 12 and the first superabsorbent polymer particles 13 constituting the absorbent portion 11. It is wrapped so as not to go out of the part 11. Further, the first core material covering sheet 3 a also acts to appropriately diffuse moisture in excreta such as urine after passing through the top sheet 2 in the vertical direction A and the horizontal direction B.
- tissue paper is used for the first and second core material covering sheets 3a and 3b.
- Preferred tissue paper has a mass of 10-25 g / m 2 .

- Inclusion compound fragrances include natural fragrances and synthetic fragrances.
- the particle 21 of the clathrate compound is adjusted to a particle size of 5 to 100 ⁇ m, preferably 10 to 50 ⁇ m by appropriately adding a water-soluble thickener such as maltodextrin, pullulan, gum arabic, etc. to cyclodextrin.
- the second superabsorbent polymer particles 22 are used in an amount 5 to 100 times the mass of the inclusion compound particles 21.
- the inclusion compound particles 21 and the second superabsorbent polymer particles 22 are premixed and dispersed on the upper surface 16a of the core 16 at a mass ratio of 15 to 110 g / m 2 . Since the amount of the inclusion compound particles 21 used per 1 m 2 of the upper surface 16a is small, for example, a mass of about 0.5 to 10 g / m 2 suffices. Therefore, the inclusion compound particles 21 are mixed with the second superabsorbent polymer particles 22. It becomes easy to make the absorption part 11 by increasing the apparent bulk and spraying. As the first superabsorbent polymer particle 13, the same one as the second superabsorbent polymer particle 22 can be used.

- the first core material covering sheet 3a and the core material 16 are in close contact with each other so as not to be substantially peeled off.
- the phrase “substantially not peeled” here means that the first core material covering sheet 3 a and the core material 16 do not peel when the processing sheet 1 is normally handled or used.
- a liquid absorption area 25 is defined.
- the inclusion compound particles 21 in which the fragrance is included between the first core material covering sheet 3 a and the core material 16 and the second superabsorbent polymer particles 22 form the fragrance spreading layer 20.
- the first core material covering sheet 3 a formed of tissue paper has a low tear strength and is covered and protected by the top sheet 2.
- the inclusion compound particles 21 and the highly water-absorbing polymer particles 22 in the liquid absorption region 25 are also formed in the longitudinal direction A by the first core material covering sheet 3a integrated with the core material 16 at the bottom 6a of the pressing groove 6. Even in the lateral direction B and above the thickness direction C, the liquid absorbing region 25 does not go out.

It is suitable for use as the first core material covering sheet 3a. In the liquid absorption region 25, the inclusion compound particles 21 and the second superabsorbent polymer particles 22 are also compressed so as not to enter the core 16.
- the pulverized pulp is compressed so as to maintain a density of 0.03 to 0.15 g / cc. Therefore, even if the treatment sheet 1 is folded or rolled before using it, the distribution of the inclusion compound particles 21 and the second superabsorbent polymer particles 22 is not biased.
- the preferred liquid absorption region 25 is made to have a size such that the surface area is 0.05 to 5 cm 2 . When the liquid absorption area 25 is like this, in the treatment sheet 1, urine does not diffuse widely, and the leg of the pet animal is not stained with urine.
- the treatment sheet 1 thus formed can be used in the same manner as a conventional treatment sheet.
- this treatment sheet 1 for example, when urine is excreted thereon and enters the liquid absorption area 25, a part of the urine dissolves the cyclodextrin in the particles 21 of the clathrate compound, and the fragrance that has been clathrated Generates odor and masks urine odor. Part of the urine is also absorbed by the second superabsorbent polymer particles 22 or the core material 16.
