Specifically, the plurality of first embossed portions 21 and the plurality of second embossed portions 31 are arranged in a matrix. When viewed along the overlapping direction, the plurality of first embossed portions 21 and the plurality of second embossed portions 31 form the second outer layer along the overlapping direction. The plurality of second embossed portions 31 of 3 are arranged alternately in a matrix so as to respectively correspond to the portions where the second embossed portions 31 are not provided, thereby mutually supplementing the portions where the water repellency is insufficient. In this embodiment, each of the first embossed portions 21 and each of the second embossed portions 31 are circular holes, and may be holes of other shapes in other embodiments.

Here, the plurality of first embossed portions 21 are embossed from at least one side along the overlapping direction of the first outer layer 2, and the plurality of second embossed portions 31 are formed on the second outer layer 3. It is embossed from at least one side along the overlapping direction. In this embodiment, a plurality of the first embossed portions 21 and a plurality of the second embossed portions 31 are embossed on opposite sides of the first outer layer 2 and the second outer layer 3, respectively, so that the It has a strong fixing effect and avoids loosening of the structure.

Furthermore, the first outer layer 2 has a first convex portion 22 between any two adjacent first embossed portions 21, and the second outer layer 3 has any two adjacent first embossed portions 21. A second convex portion 32 is formed between the second embossed portions 31, each of the first convex portions 22 abuts on the second embossed portion 31 along the overlapping direction, and each of the second convex portions 32 contacts the first embossed portion 21 along the overlapping direction. This avoids overlapping of the plurality of first embossed portions 21 and the plurality of second embossed portions 31, and each of the first convex portions 22 abuts on the second embossed portion 31, and each The contact of the second convex portion 32 with the first embossed portion 21 improves the frictional force between the first outer layer 2 and the second outer layer 3 to avoid sliding.

Here, the thickness of the first embossed portion 21 is 0.25 to 0.5 times the thickness of the first convex portion 22, and the thickness of the second embossed portion 31 is the thickness of the second convex portion. It is 0.25 to 0.5 times the thickness of the portion 32 . In this embodiment, both are 0.375 times, the first outer layer 2 and the second outer layer 3 are less likely to loosen, and the plurality of first embossed portions 21 and the second embossed portions 31 are thin.
