Abstract: The present invention relates to a method of manufacturing non-sintered liquid metal ink, and more particularly, to a method of manufacturing liquid metal ink manufactured without a sintering process. The method of manufacturing liquid metal ink according to an embodiment of the present invention includes: (a) inputting a solvent into liquid metal in a container at room temperature; (b) performing oxide film-removing treatment on the liquid metal of step (a); and (c) dispersing the liquid metal that has undergone step (b) in a form of nanoparticles through ultrasonic treatment.
