Abstract
A nozzle and an electrostatic field induction ink-jet nozzle are disclosed. In accordance with an embodiment of the present invention, the nozzle includes a concave part, which is formed along an outer circumference of the nozzle and in which the outer circumference is adjacent to a liquid discharging surface. The discharging nozzle can minimize the overflow and damping by a liquid during a process of discharging the liquid and thus maintain the discharging performance constant despite an extended operation of the nozzle.
