PURPOSE: A monolithic printer head is provided to improve productivity and quality with an adjacent nozzle and to discharge ink stably by uniting the incoming and discharging direction of ink. CONSTITUTION: A monolithic printer head is composed of a substrate(10) made of glass or silicone, a heater(20) formed onto an upper surface of the substrate(10), a nozzle plate(40) stacked onto the upper surface of the substrate and having a nozzle(41) for discharging an ink, a cavity shape of a pressure room(30) which is connected with the nozzle, and an ink supplying passage(50) which is passing through the substrate vertically to the surface of the heater. A drive circuit part for driving the heater(20) is formed at the substrate(10). An electrode(61) and a metal wire(62) for connecting electrically the drive circuit part with the heater are formed onto the upper surface of the substrate. The pressure room(30) is formed at a lower portion of the nozzle.
