PURPOSE: A method of manufacturing a gold nano fluid using an ultrasonic generation water tank is provided to use a dispersion energy source which generates gold nano particles uniformly by preventing not only a chemical reaction but also thermal energy for activating a reduction reaction from being generated locally. CONSTITUTION: A method of manufacturing a gold nano fluid using an ultrasonic generation water tank comprises the following steps: a water temperature inside an ultrasonic water tank is maintained with 80 to 90°C; a chloroauric acid aqueous solution consisting of 0.25 mM of a molarity is put into a container; after the container is fixed inside the ultrasonic water tank, ultrasonic energy is given; a sodium citrate aqueous solution is injected within the container in order to make 1 : 3.5 of a molar fraction of a chloroauric acid and a sodium citrate in the chloroauric acid aqueous solution within the container; and the ultrasonic energy is given within the ultrasonic water tank again.
