ABSTRACT:
In a piezoelectric ink-jet printhead, and a method of manufacturing a nozzle plate, the piezoelectric ink-jet printhead includes a flow path plate having an ink flow path including pressure chambers to be filled with ink to be ejected, a piezoelectric actuator formed on an upper surface of the flow path plate and for supplying a driving force for ink ejection to the pressure chambers, and a nozzle plate bonded to a lower surface of the flow path plate including nozzles for ejecting ink from the pressure chambers bored through the nozzle plate. The printhead may further include a heater formed on a lower surface of the nozzle plate for heating ink in the ink flow path and/or a temperature detector formed on a lower surface of the nozzle plate or on an upper surface of the flow path plate.
