INK JET PRINT HEAD AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An ink jet print head and a method for manufacturing the same are provided to obtain an ink jet print head having an improved structure capable of enhancing performance thereof. CONSTITUTION: An ink jet print head includes a substrate(100). An ink chamber(106) filled up with ink is formed at a surface of the substrate. A restrictor(108), which is a path for providing ink from an ink storage(200) to the ink chamber(106), is formed by passing through a rear surface of the substrate(100) from a bottom surface of the ink chamber(106). A nozzle plate(120) is stacked on a surface of the substrate(100) to form an upper well of the ink chamber(106). The nozzle plate includes a nozzle(104) formed at a position corresponding to a center of the ink chamber(106). A conductor(124) is formed at an internal portion of the nozzle plate(120) to apply current to a heater(122).
