ABSTRACT:
An ink jet head, having a long life, capable of discharging ink with a strong force and at a high speed is provided at a small size. A container comprises a casing and a nozzle plate covering the upper surface of the casing and an ink discharge opening. A buckling structure is fixed at its longitudinal ends to the bottom surface of the container via an installing member, and its center portion can be deformed upward by buckling. A diaphragm is positioned above the buckling structure with a space therebetween and placed on an inner wall of the casing with its periphery fixed thereto so as to liquid-tightly partition the inside of the container into a space and an ink chamber. A connection member connects the diaphragm and the buckling structure at their center. Electrodes are provided at both ends of the buckling structure to generate thermal stress therein by supplying electric current for buckling and consequently to apply pressure to ink in the ink chamber for discharging.
