Liquid discharge head, head module, liquid discharge unit, and liquid discharge apparatus

Abstract

A liquid discharge head includes a chamber substrate, a nozzle substrate, a damper, and a frame substrate. The chamber substrate includes a pressure chamber and a pressure generator to change a volume of the pressure chamber. The chamber substrate has a first face and a second face opposite to the first face. The nozzle substrate is disposed on the first face in a lamination direction. The nozzle substrate has a nozzle communicating with the pressure chamber. The damper is disposed on the second face in the lamination direction. The frame substrate is disposed over the damper in the lamination direction. The chamber substrate has a first area in an in-plane direction of the chamber substrate. The nozzle substrate has a second area smaller than the first area in the in-plane direction. The frame substrate has a third area larger than the first area in the in-plane direction.
