摘要： An inkjet head having an electrostatic actuator and a manufacturing method of the same are disclosed. The inkjet head having an electrostatic actuator, comprising a stator, on which is formed a plurality of comb pattern shaped first protrusion parts and second protrusion parts in both directions, and a rotor consisting of a first component and a second component, the ends of which join with the diaphragm, wherein a third protrusion part is formed on the first component, facing the first protrusion parts and meshing with the first protrusion parts without contact; and a fourth protrusion part is formed on the second component, facing the second protrusion parts and meshing with the second protrusion parts without contact, may decrease the size of the head composition and may increase the electrostatic force so that a large displacement may be obtained with little voltage to increase the ink discharge pressure.
