ABSTRACT:
A liquid discharge head include a discharge port for discharging liquid; a liquid chamber communicating to the discharge port; a piezoelectric element including one electrode layer, another electrode layer, and a piezoelectric film sandwiched between the one electrode layer and the other electrode layer independently arranged in correspondence to the liquid chamber, and including a piezoelectric drive portion at where the piezoelectric film deforms and displaces in correspondence to the liquid chamber; and a vibration plate interposed between the piezoelectric element and the liquid chamber, wherein a bending rigidity of both ends in an arranging direction of the one electrode layer of a portion corresponding to the piezoelectric drive portion of the vibration plate is greater than the bending rigidity of a region between both ends.
