摘要:
In a method of manufacturing a liquid jet head, a piezoelectric substrate is bonded onto a first base. Ejection grooves for ejection channels and dummy grooves for dummy channels are alternately formed in parallel with one another. The ejection grooves and the dummy grooves have such a depth as to pierce the piezoelectric substrate and to reach the first base substrate. An electrode material is deposited on inner surfaces of the ejection grooves and the dummy grooves. A cover plate is bonded to the piezoelectric substrate so as to cover the ejection grooves and the dummy grooves. In a subsequent first base substrate removing step, a part of the first base substrate on a side opposite to the cover plate and the electrode material deposited on bottom surfaces of the dummy grooves are removed. A second base substrate is then bonded to the first base substrate.
