Liquid jet head having common and active electrodes

摘要

A liquid jet head 1 comprises an actuator substrate 2 having ejection grooves 6a and non-ejection grooves 6b partitioned by walls 5. The non-ejection grooves have inclined surfaces (22, Fig.2A) at either end thereof. Common electrodes 12a are provided in strip form along the walls 5 on both side surfaces of the walls 5 facing the ejection grooves 6a. Active electrodes 12b are provided in strip form along the walls 5 on both side surfaces of the walls 5 facing the non-ejection grooves 6b. The active electrodes 12b are provided from positions in the vicinity of one end of the non-ejection groove 6b to the other end thereof. The head may be provided with a cover plate 3 and a nozzle plate 4. There is also provided a method of manufacturing a liquid jet head including the accumulating a conductive body on a piezoelectric substrate using an oblique deposition method.
