Abstract
A liquid discharge head includes an actuator substrate, a holding substrate, a common-liquid-chamber substrate, and a vibration absorber. The actuator substrate includes a plurality of individual liquid chambers and a plurality of pressure generating elements. The individual liquid chambers are communicated with a plurality of nozzles to discharge liquid. The pressure generating elements are arrayed to pressurize liquid in the individual liquid chambers. The holding substrate includes a recessed portion to accommodate the pressure generating elements. The common-liquid-chamber substrate includes a common liquid chamber to supply the liquid to the individual liquid chambers. The common-liquid-chamber substrate is bonded to the holding substrate. The vibration absorber is disposed at at least a part of a bonded portion of the common-liquid-chamber substrate and the holding substrate, to absorb vibration. The holding substrate has an opening as a channel communicating the individual liquid chambers with the common liquid chamber.
