The present invention relates to a device for discharging ink using electrostatic force, and the device for discharging ink using electrostatic force, according to the present invention, comprises: a nozzle portion for spraying ink on a substrate through an electric field; an electrode portion for forming the electric field between the nozzle and the substrate; and a gas spraying portion for spraying guide gas from an outer side of the nozzle portion so as to control the cross-sectional area of the ink that is discharged from the nozzle portion. As a result, by controlling a droplet that is formed on the nozzle portion by spraying the guide gas or the ink that is discharged, the diameter or a line width of a pattern that is shot onto the substrate can be rendered to be very fine. |
