ABSTRACT:
An ink jet head is provided with a channel body and a piezo-electric actuator connected with the channel body. The channel body is provided with a plurality of ink flow channels. Each of the ink flow channel has a pressure chamber and a nozzle connected with the pressure chamber. The piezo-electric actuator is provided with a piezo-electric layer. The piezo-electric layer has a plurality of high piezo-electric characteristic areas and a low piezo-electric characteristic area. Each of the high piezo-electric characteristic areas faces each of the pressure chambers of the channel body. The low piezo-electric characteristic area faces an intermediate area between the pressure chambers.
