To provide an inkjet head having an improved ink ejection speed and frequency and a method of manufacturing such an inkjet head.
The inkjet head is equipped with a channel damper D, and its manufacturing method is disclosed. The inkjet head is equipped with a substrate S and a heat-generating resistor R disposed on the substrate S to generate pressure for ink ejection. A chamber layer C is disposed on the substrate S to enclose the heat-generating resistor R and having a first height from the substrate S in order to provide at least one opened part O. A channel damper D having a second height lower than the first height is disposed at the opened part O so as to completely enclose the heat-generating resistor R together with the chamber layer C. A nozzle layer having a nozzle N corresponding to the heat-generating resistor R is disposed to be in contact with an upper surface of the chamber layer C.
