Abstract:
A method of manufacturing a multi-layer ink jet recording head, comprising:laminating a green sheet of zirconia whose thickness is suitable for formation of an elastic board, a green sheet of zirconia having through-holes for forming pressure generating chambers, a green sheet of zirconia having through-holes serving as flow path regulating holes, through-holes communicating with nozzle openings, and a through-hole through which ink is supplied into a common ink chamber, and a green sheet of zirconia having a window for forming the common ink chamber and through-holes through which the nozzle openings are communicated with the pressure chambers, to form a stack of green sheets;sintering the stack of green sheets;forming a pattern of drive electrodes on a surface of the elastic board and forming piezo-electric vibrators over the drive electrodes by applying a piezo-electric material to the elastic board and sintering the piezo-electric material; andbonding, with an adhesive, a nozzle plate having the nozzle openings to a common-ink-chamber forming board which is formed by the sintering of the green sheet having the window.
