Abstract
A liquid discharge head includes a nozzle plate having nozzles arrayed to discharge liquid droplets; a passage plate to form individual liquid chambers communicating with the respective nozzles; and a wall surface member to form a wall surface of the individual liquid chambers. The passage plate is formed with at least three plate-shaped members stacked and bonded by an adhesive. The nozzle plate and one plate-shaped member, and another plate-shaped member and the wall surface member are bonded, respectively. The three plate-shaped members include separation wall parts forming separation walls between the individual liquid chambers. At least one of the three plate-shaped members has a separation wall width different from that of the others, to have fillets of the forced-out adhesive formed between the wall surfaces, and surfaces of the plate-shaped members, the nozzle plate, or the wall surface member.
