A manufacturing method of metal nano ink is provided to obtain metal nano ink of high concentration by increasing the content of metal nanoparticles which are a solid powder. A manufacturing method of metal nano ink for the ink jet comprises (i) a step for preparing the first mixture solution by mixing metal nanoparticles capable of being monodispersed, in the first dispersion solvent having a boiling point which relatively is lower than that of the second dispersion solvent and agitating it; (ii) a step for preparing the second mixture by mixing the first dispersion solvent and the second dispersion solvent having the boiling point which is relatively higher than the first dispersion solvent and agitating it; and a step for removing the first dispersion solvent by using a classification distillation method. |
