    摘要: An ink jet print head includes a plural number of piezoelectric vibrators each consisting of a lower electrode film, a piezoelectric film and an upper electrode film. The piezoelectric film and the upper electrode film of each piezoelectric vibrator are formed within the region facing each pressure generating chamber. The lower electrode films interconnect portions of the regions facing the pressure generating chambers and are electrically continuous to a wiring pattern connected to an external circuit, and in each of the portions of the regions facing the pressure generating chambers, each portion not having the piezoelectric vibrator is removed except a part thereof. Such a structure secures a satisfactory function of the lower electrode layer as a common electrode, increases a quantity of displacement of the piezoelectric vibrator while keeping a low compliance, increases an ink discharging speed, and reduces a drive voltage.
