Abstract:
A liquid jet head has spaced-apart side walls that form alternating ejection channels and non-ejection channels. The side walls comprise two piezoelectric materials polarized in opposite directions and laminated together with a polarization boundary interposed between them. Upper and lower members are fixed to respective upper and lower ends of the side walls and overlie upper and lower ends of the channels. Electrodes on opposed wall surfaces of the side walls extend from the upper ends of the side walls to either the vicinity of the polarization boundary or to below the polarization boundary and above the lower ends of the side walls. The polarization boundary is positioned above one-half the depth of the channels to improving the driving efficiency of the piezoelectric body.
