Abstract
A nonwoven fabric facilitating permeation of loose passage. A nonwoven fabric is formed of short fibers of thermoplastic synthetic resin fused together. The nonwoven fabric is formed on a top side thereof with ridges and troughs undulating in a width direction and extending in parallel to one another in a length direction. When the nonwoven fabric is placed on a horizontal plane with the back side put in contact with the horizontal plate, highly void regions are formed between the back side and the horizontal plane. In the vicinity of apices of the respective ridges, the short fibers slope down so as to extend in a thickness direction of the nonwoven fabric.
