A nonwoven fabric that is regulated in at least one of fiber orientation, fiber compression and fiber weight per area, or provided with at least one of given groove portion (1), open area (3) and projecting portion (2, 7); and a process for producing the nonwoven fabric and apparatus therefor. The nonwoven fabric production apparatus is structured so as to blow a fluid composed mainly of a gas against a sheet-shaped fiber assembly wherein at least some of the fibers constituting the fiber assembly are contained in free form to thereby produce a nonwoven fabric that is regulated in at least one of fiber orientation, fiber compression and fiber weight per area, or provided with at least one of given groove portion, open area and projecting portion. |
