ABSTRACT OF THE DISCLOSURE A fine bubble generating apparatus aiming at reducing diameters of bubbles generated through outer surface of a hollow yarn by giving a running speed to liquid contacting the surface of the yarn without utilizing mechanical power developed by a pump or the like. The fine bubble generating apparatus comprises a cylindrical device (1, 4 or 11) which is open in the upper and lower ends thereof and disposed in a liquid stored in a liquid vessel (8), the lower of the cylindrical device spaced apart from the inner surface of the bottom of the vessel; a passage (6 or 6a) which is narrow in width and formed inside the cylindrical device so as to extend vertically and whose upper and lower ends are open; a hollow yarn (3) which has a predetermined length and is inserted and held in the passage so as to be spaced apart from the inner surface of the passage and whose leading end is blocked; and a pressurized gas supply pipe connected to an open base end of the hollow yarn to supply pressurized gas into the interior of the yarn. - 24 -
