ABSTRACT:
An ink jet of the present invention includes a nozzle plate having a nozzle orifice, a substrate having an opening communicating with the nozzle orifice, an ink discharge plate having a center portion positioned in the nozzle orifice of the nozzle plate and the opening, and both ends supported by being sandwiched between the nozzle plate and the substrate, the center portion being closer to the nozzle plate than the both ends, and a compressive member for applying a compressive force in the axis direction of the ink jet plate so that the center portion of the ink discharge plate is deformed towards the nozzle orifice by buckling. Because of this structure, the ink discharge plate is always buckled towards the nozzle orifice, and forms an ink droplet without erroneous operation.
