Abstract:
1. A nonwoven fabric, comprising: short fibers fused together, a top side and a back side, wherein the top side is formed with in a cross-section of the nonwoven fabric taken in a second direction orthogonal to the first direction with the back side placed on a horizontal plane, the nonwoven fabric has highly void regions larger than interstices among the short fibers, the highly void regions are formed between the back side of the ridges and the horizontal plane, the short fibers at least in the vicinities of apices of the ridges slope downward to extend in a thickness direction of the nonwoven fabric, in the cross-section of the nonwoven fabric, an area ratio of highly void regions defined by a ratio of a first sum to a second sum is at least 3.5%, wherein an elastic height recovery rate of the ridges as measured after the top side has been subjected to a load of 20 g/cm
