The present invention relates to a manufacturing method of metallic ink. The manufacturing method of metallic ink according to the present invention comprises the step of: making metallic precursor ink and metallic nanoparticles separately from a metallic precursor having a substituent at the alpha position, followed by mixing the metallic precursor ink and the metallic nanoparticles. The metallic ink has excellent dispersion stability and can increase the metal filling ratio in a coat film, thereby improving physical properties as a result.
