A liquid jet head according to an embodiment of the present invention includes an actuator substrate formed by arraying a plurality of grooves, which penetrates from an upper surface to a lower surface of the actuator substrate and is long in a surface direction, a cover plate provided at the actuator substrate so as to cover an upper surface opening of the groove, and a nozzle plate provided at the actuator substrate so as to cover a lower surface opening of the groove. The groove includes an ejection groove and a non-ejection groove which are alternately arrayed, and is formed in such a manner that configurations of the lower surface openings of the ejection groove and the non-ejection groove are different. |
