Although FIG. 4B shows a state in which the four corners of the pad 1 are projected from the inside of the recess formed on the surface sheet 2 side of the pad 1, these four corners are also inside the recess. It can also be stored and used.

According to the urine absorbing pad 1 of this embodiment,
The shape can be easily transformed into a shape suitable for exhibiting the absorption performance (for example, the shape shown in FIG. 4B or 4C), and the shape is stably maintained during wearing. Therefore, not only excellent absorption performance is obtained, but also positional deviation during wear is prevented, and further, there is an advantage that the liquid excretion part 8 of a man can be worn without touching it directly. In particular, in the present embodiment, as shown in FIG. 3, since the end portions in the longitudinal direction of the inner edge portions 62 of the two sheet-shaped members 6 are overlapped with each other, the side edge portion (where the elastic member is disposed ( The central portion of the pad 1 pressed between the inner edge portions 62 is pressed from the entire periphery thereof. Therefore, a deeper dent can be formed, and the shape retention of the deformed shape during wearing is further excellent.

As shown in FIG. 2, the absorbent body 4 in this embodiment includes a central absorbent body 41, side absorbent bodies 42, 42 on both sides of the central absorbent body 41, and a liquid-permeable cover sheet 43 for covering them. The boundary portion between the central absorbent body 41 and both side absorbent bodies 42 functions as a flexible shaft 44 that improves the ease of bending of the absorbent body 4. The flexible shaft 44 is attached to the absorber 4.
By providing, the degree of freedom of deformation of the absorber is increased, a deeper dent can be formed on the surface sheet 2 side, and wearability on the wearer and absorption performance can be further improved. As shown in FIG. 2, it is preferable that the flexible shaft 44 is provided at a portion overlapping the outer edge 63 of the sheet-shaped member 6. As a method of forming the flexible shaft on the absorber,
Instead of the method of the present embodiment, it is also possible to use a method such as giving an embossed line to the absorber 4 or forming a slit in the absorber 4. The cover sheet 43 is a liquid-permeable sheet made of paper or non-woven fabric, and forms the surface of the absorber.
