The present invention provides a liquid atomizing nozzle capable of atomizing liquid materials of highly viscous or containing bulky solid materials charged not only at a small feed rate but also at several thousands liter/hr rate, by which the liquid is atomized and sprayed uniformly with a predetermined spray angles. A liquid atomizing nozzle of the invention comprises a liquid supplying pipe; a cylindrical chamber for whirling of air being connected at one end with the liquid supplying pipe, having an inside diameter larger than inside diameter of the liquid supplying pipe, and being provided with one or more through holes for passing through pressurized air in the direction tangential to circular internal surface of the cylindrical chamber; an orifice disposed at the top of the cylindrical chamber and having a circular opening of smaller than inside diameter of the cylindrical chamber; and an external cylinder covering over the cylindrical chamber and at least a part of the liquid supplying pipe and being provided with a pressurized air supplying pipe.
