    摘要： An ink jet print head includes a plural number of piezoelectric vibrators (300) each consisting of a lower electrode film (60), a piezoelectric film (70) and an upper electrode film (80). The piezoelectric film and the upper electrode film of each piezoelectric vibrator are formed within the region facing each pressure generating chamber (12). 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.

    摘要： An ink jet recording head is provided with a piezoelectric vibrator. The piezoelectric vibrator consists of a diaphragm and a piezoelectric active part. The diaphragm includes a pressure generating chamber communicating with a nozzle aperture, at least the upper surface of which acts as a lower electrode. The piezoelectric active part consists of a piezoelectric film formed on the surface of the diaphragm and an upper electrode formed on the surface of the piezoelectric film, formed in an area opposite to the pressure generating chamber. A cap member is bonded on one side of the piezoelectric film for sealing a space with a holder to the extent that the motion is secured. The piezoelectric active part is cut off from the outside of the head by sealing dry fluid in the space of the cap member.
