Liquid discharge head

Abstract

To provide a liquid discharge head that is configured so that positional accuracy between a vibration plate and an actuator can be improved.SOLUTION: A liquid discharge head according to one embodiment comprises a vibration plate, and comprises a passage member having a liquid passage comprising a plurality of pressure chambers, a piezoelectric member, oppositely arranged at the vibration plate, which comprises a driving element that generates pressure in the pressure chambers, and a nozzle plate, oppositely arranged at the opposite side of the vibration plate of the passage member, which has a plurality of nozzles that discharge liquid droplets. The piezoelectric member has a plurality of drive elements arranged in a first region opposed to a pressure area in which the pressure chambers are arranged, and a plurality of columnar elements arranged in a second region other than the first region. The vibration plate comprises an alignment part having one or a plurality of alignment marks, at a position opposed to the second region of the piezoelectric member.SELECTED DRAWING: Figure 5
