摘要： 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.

摘要： A liquid discharge head includes a nozzle plate, a channel plate, a common channel substrate, and a wall member. The nozzle plate includes a plurality of nozzles configured to discharge liquid. The channel plate includes a plurality of pressure chambers communicated with the nozzles, respectively. The common channel substrate includes a common channel communicated with the pressure chambers. The wall member includes a deformable region in a part of a wall surface of the common channel. The channel plate and the common channel substrate are disposed with the wall member interposed between the channel plate and the common channel substrate. The channel plate includes an air chamber facing the deformable region. The channel plate includes a bridge portion partially dividing the air chamber in a nozzle arrangement direction in which the nozzles are arranged. The bridge portion is not in contact with the wall member and the nozzle plate.
