    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.
