<P>PROBLEM TO BE SOLVED: To prevent body fluid from staying at the hill parts of a nonwoven fabric formed with hill parts and valley parts extending in one direction in parallel with each other. <P>SOLUTION: This nonwoven fabric 1 is formed by fusing short fibers 11 of thermoplastic synthetic fibers with each other. On the surface 2 of the nonwoven fabric, there are formed the hill parts 6 and valley parts 7 extending in parallel with each other. At the hill parts 6, there are included first hill parts 6a having a higher height from the reverse surface 3 of the nonwoven fabric 1 and second hill parts 6b having a lower height. The density of the nonwoven fabric 1 becomes higher in the order of the first hill parts 6a, second hill parts 6b, and the valley parts 7. The first hill part 6a is formed so that the density of the first hill part 6a may become lower than that of the second hill part 6b when the first hill part 6a is compressed toward the reverse surface 3 and becomes the same height with that of the second hill part 6b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
