Abstract
Official abstract text for this publication.
A liquid jet head includes an actuator substrate having a plurality of elongated grooves arrayed from an upper surface to a lower surface thereof. The grooves are formed from a vicinity of a peripheral end on one side of the actuator substrate to a peripheral end the other side thereof, ends of the grooves in a longitudinal direction thereof have respective inclined surfaces rising from the lower surface to the upper surface of the actuator substrate, and a crossing angle at crossing portions at which the inclined surfaces and the lower surface cross each other is in a range of 3 degrees to 80 degrees. A width W of the inclined surfaces in the longitudinal direction thereof and a thickness D of the actuator substrate satisfy a relationship 0.2≦(W/D)≦11 at the ends on one side of the grooves.
