A method for manufacturing a conductive film, the method comprising the steps of: preparing a mixture liquid in which a catalytic metal is dispersed in a precursor or a precursor compound of a two-dimensional nanomaterial; and forming a catalytic metal/two-dimensional nanomaterial by irradiating the mixture liquid with ultrasonic waves to generate microbubbles, degrading the precursor compound using energy, which is generated when the microbubbles burst, to synthesize the two-dimensional nanomaterial on an outer wall of the catalytic metal, wherein the method further comprises: dispersing the catalytic metal/two-dimensional nanomaterial in a dispersion to prepare ink; and applying the ink on a substrate and performing rapid air-sintering. Thus, the two-dimensional nanomaterial is synthesized on an outer wall of a non-noble metal having high oxidative characteristics, thereby preventing oxidation of the metal from air and increasing thermal conductivity and electrical conductivity.
