Abstract
A liquid discharge head includes a nozzle plate, a channel substrate, a common-liquid-chamber substrate, an adhesive, and a sealant. The nozzle plate includes a plurality of nozzles to discharge liquid. The channel substrate includes a plurality of individual liquid chambers communicated with the plurality of nozzles. The common-liquid-chamber substrate includes a common liquid chamber to supply the liquid to the plurality of individual liquid chambers. The adhesive bonds two of the nozzle plate, the channel substrate, and the common-liquid-chamber substrate. The adhesive faces a channel through which the liquid flows. The sealant surrounds the adhesive at an opposite side of the channel relative to the adhesive.
