ABSTRACT:
An ink jet print head 10 of the invention comprises a base plate 12 which includes a nozzle hole 14 and an ink supply channel 20 in one surface thereof and an actuator 30 which is bonded on the one surface of the base plate 12 to cover the nozzle hole and ink supply channel. The actuator 30 is formed in one surface adjacent to the base plate with an ink chamber 32 which connects the ink supply channel 20 and the nozzle hole 14. The ink chamber 32 and nozzle hole 14 are filled with an ink material, and the ink material is ejected through the nozzle hole 14 when it is pressurized by the actuator 30. According to the ink jet print head 10 of the invention, the number of parts constituting the head can be reduced, and a shorter production process and a lower production cost can be achieved.
