摘要： In an ink jet recording head, after a plate-shaped piezoelectric element is positioned and fixed onto a fixing plate, the piezoelectric element is sliced into a large number of vibrators and the leading ends of the vibrators are embracingly held in positioning holes 33 respectively formed in a top surface of a holding frame and are thus positioned in the surface direction thereof. Further, a cavity unit is positioned and fixed on the top surface of the holding frame.
