<p>A liquid jet head 1 is provided with an actuator substrate 2 partitioned by elongated walls 5 of a piezoelectric body and having elongated ejection grooves 6a and elongated non-ejection grooves 6b alternately arrayed thereon so as to penetrate the actuator substrate from an upper surface US through a lower surface LS thereof. There may be provided a cover plate 3 provided on the upper surface US and having first slits 14a communicating with the ejection grooves 6a on one side and second slits 14b communicating with the ejection grooves 6a on the other side; and a nozzle plate 4 provided on the lower surface LS and having nozzles 11 communicating with the ejection grooves 6a. The non-ejection grooves 6b extend, on the other side, up to a second-side peripheral end of the actuator substrate 2, and the actuator substrate 2 is left to form raised bottom portions 15 on bottoms of the non-ejection grooves 6b near the second-side peripheral end. There is also provided a method of manufacturing the liquid jet head 1.</p> |
