PROBLEM TO BE SOLVED: To provide a liquid discharge head which can improve the positioning accuracy of a nozzle plate or the like.SOLUTION: A nozzle plate is positioned in Y direction, by using a joint boundary 203 between a first piezoelectric substrate 501 and a second piezoelectric substrate 502, and a diagonal line of a rear restriction plate alignment hole 810. A wall of an individual liquid chamber 307 is formed of piezoelectric material, and functions as a pressure chamber. Four sides around the individual liquid chamber 307 are provided with an air chamber 308 via a piezoelectric member. |
