Abstract: A liquid jet head includes an actuator substrate having ejection grooves and non-ejection grooves partitioned by walls each including a piezoelectric body. The non-ejection grooves have, at ends on one side thereof, respective inclined surfaces rising from bottom surfaces thereof to upper surface openings at upper portions thereof. Common electrodes are provided in a strip form along a longitudinal direction of the walls on both side surfaces of the walls facing the ejection grooves, and active electrodes are provided in a strip form along the longitudinal direction of the walls on both side surfaces of the walls facing the non-ejection grooves. The active electrodes extend from positions in the vicinity of the ends on one side of the non-ejection grooves to ends on the other side thereof.
