    摘要: A liquid-drop ejection device having a plurality of ejectors each having a variable-capacity ink channel. The capacity of the ink channels is variable to generate sufficient pressure to thereby eject ink in the ink channels from nozzles communicating with the ink channels onto paper or the like. The ejection device further comprises a piezoelectric transducer having a plurality of walls for separating the ink channels from one another. The walls have drive electrodes formed on upper or lower portions. The upper portions of the walls are narrower in width than the lower portions. A method of forming the ejection device comprises a first step of forming grooves including portions for receiving drive electrodes, a second step of forming the drive electrodes in the grooves and a third step of further forming the grooves to provide additional portions having widths different from the portions of the grooves formed in the first step.
