Abstract

A liquid discharge head (1) includes an actuator component (2) and a frame (3). The actuator component (2) includes a nozzle substrate (10) and an actuator substrate (20). The nozzle substrate (10) has nozzles (10a) arrayed in a longitudinal direction. The actuator substrate (20) includes a chamber substrate (21), a diaphragm (22), and a piezoelectric element (23). The chamber substrate (21) has pressure chambers (21b) respectively communicating with the nozzles (10a). The diaphragm (22) has a first face serving as a part of a wall face of the pressure chambers (21b) and a second face opposite the first face. The piezoelectric element (23) is disposed over the second face of the diaphragm (22). The frame (3) has a bonding face (3d) bonded to the actuator component (2) with an adhesive (50), communicating portions (3a) communicating with the pressure chambers (21b), and multiple void portions (3b).
