PURPOSE: An ink-jet printer head is provided to prevent clogging of a nozzle and remove impurities by generating bubbles by instant heating in case of head cleaning, for omitting an additional suction element, thereby simplifying the structure of the printer while reducing unnecessary consumption of ink, cleaning time period and noise. CONSTITUTION: An ink-jet printer head includes a fluid channel plate(10) formed with a reservoir(11) and a restrictor(12) formed at a side of a chamber(13) to introduce ink, and a fluid channel(14) and a nozzle(15) formed at the other side of the chamber to discharge the ink, a micro actuator(20) having a piezo-electric element mounted right immediately on the chamber of the fluid channel plate and coupled with an electrode, and a bubble generating element(30) evaporated on a bottom surface of the chamber for heating the ink in the chamber up to a predetermined temperature to generate bubbles, wherein the temperature is to be 200°C.
