Abstract
A liquid discharge head includes: a nozzle plate having a nozzle configured to discharge liquid in a discharge direction; a channel plate over the nozzle plate, the channel plate having: a pressure chamber; multiple flow restrictors: each communicating with the pressure chamber common to each of the multiple flow restrictors; overlapped with each other in the discharge direction; and each having a same length in a longitudinal direction orthogonal to the discharge direction; an individual chamber communicating with the pressure chamber through the multiple flow restrictors; and a pressure generator configured to generate pressure in the pressure chamber.
