An object of the present invention is to provide a bulky sheet in which fiber fluffing and fiber pull-out hardly occur. A fiber assembly 11 is formed by hydroentangling fiber webs 11a and 11b. The fiber assembly 11 includes a first region 21 having a large fiber density and a small thickness, and a second region 22 having a fiber density smaller than that of the first region 21 and greater than that of the first region 21. The second area 22 is surrounded by a closed first area 21. The second area 22 has a plurality of convex portions 31 and concave portions 32. [Selection] Figure 1 |
