Abstract:
An ink jet head comprising:a base plate constituted by a solid-state actuator which deforms in response to reception of a voltage;a plurality of groove-like ink channels formed in a surface of said base plate to be parallel to each other, said ink channels being filled with ink to form ink chambers;an electrode made of a conductive material and formed on an inner surface of each of said ink channels to apply the voltage;a nozzle hole formed in one end face of said ink channel to inject the ink, the end face being perpendicular to a direction of grooves of said ink channels; andan insulating film formed on a surface of said electrode;wherein said insulating film formed on the surface of said electrode is destroyed by ultrasonic vibration to form a conductive alloy, thereby connecting a bonding wire to said electrode.
