A nonwoven short fibre fabric which comprises short fibers which have a fibre length of 3 to 25 mm and a single yarn fineness of 1 to 100 denier and which are dispersed and piled up, and nodes of which are bonded to one another. Fibre wads composed of short fibres and having a volume of at least 1 mm3 in the nonwoven fabric of 20 g are five or less in number, and the nonwoven short fibre fabric has a specific volume of 40 to 200 cm3/g. The nonwoven fabric can provide a bulky nonwoven fabric functioning sufficiently to contribute to bulkiness due to fibres, and is suitably used for sanitary materials such as disposable diapers, napkins, pads for incontinence, pads for mother's milk, or wipers.
