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 allow for stable discharge of ink and reduce crosstalk between adjacent nozzles. CONSTITUTION: An ink jet print head comprises a substrate(10); a heater(20) formed on the substrate; a pressure chamber wall(31) formed on the substrate in such a manner that the pressure chamber wall surrounds the heater; a pressure chamber(30) having a bottom surface formed by the substrate and side surfaces formed by the pressure chamber wall; an ink feeding path(50) penetrating through the substrate in the direction vertical to the surface of the heater, and which is communicated to the pressure chambers; and a nozzle plate(40) deposited on the pressure chamber, and which has a nozzle(41) for discharging ink.
