摘要：
In an ink jet recording head in which pressure chambers are formed by fastening a vibration plate to a nozzle-opening contained member, and piezoelectric vibrators, which extend and contract in the axial direction, are fastened at the fore ends to the region of the vibration plate, islands are formed in the region of the vibration plate where is to be in contact with the piezoelectric vibrators, each of the islands being surrounded by a thinned part, the fore end of each piezoelectric vibrator is fastened to each island.
