Abstract A nonwoven fabric making apparatus adapted to continuously feed a fibrous web 30 in one direction, to eject streams of high pressure fluid from a plurality of nozzles 20 against at least one surface of the web 30, thereby to entangle component fibers of the web 30 and to obtain a predetermined nonwoven fabric. On the assumption that a Y-axis extends in a direction along which the web 30 travels and an X-axis extends to intersect the Y-axis at right angles, the nozzles 20 are arranged at predetermined intervals to define a straightly extending a first nozzle array R1 which is declined at a predetermined angle with respect to the Y-axis. The nonwoven fabric obtained has no impact traces by ejection of the streams of high pressure.
