Liquid discharge head, liquid discharge apparatus, and method for manufacturing liquid discharge head

Abstract

A liquid discharge head includes a discharge port to discharge a liquid, and a liquid chamber to communicate with the discharge port, and further includes a vibrating plate, and a piezoelectric element. The vibrating plate is disposed on a surface of the liquid chamber on a side facing a surface communicating with the discharge port, and includes a plurality of layers stacked in a layered structure. The piezoelectric element is disposed on a second surface of the vibrating plate being a back surface of a first surface of the vibrating plate in contact with the liquid chamber. The vibrating plate has a recessed portion surrounded by a bottom surface and four lateral surfaces intersecting with the bottom surface on the first surface. The recessed portion penetrates through a first layer having the first surface among the plurality of layers of the vibrating plates.
