PURPOSE: An inkjet printer head for nano-patterning is provided to increase the print quality by preventing an ink tail from becoming generated by a condensed electrode layer when printing dot. CONSTITUTION: An inkjet printer head for nano-patterning is composed of an ink supply channel, a jet chamber, a nozzle unit, a condensed electrode layer(52), and a ground electrode layer(54). The jet chamber is connected to the ink supply channel. The nozzle unit is formed on the end of the jet chamber. A positive voltage or a negative voltage is applied to the nozzle unit and the ink is charged to a positive charge or a negative charge. The condensed electrode layer is located on the lower part of the nozzle unit and condenses the ink discharged from the nozzle unit with the electric field. The ground electrode layer is located on the lower part of the condensed electrode layer and the current having a polarity opposite to that of the current applied to the nozzle unit is applied to the ground electrode layer and discharges the ink.
