摘要：
In an ink jet recording head, after a plate-shaped piezoelectric element (1) is positioned and fixed onto a fixing plate (2), the piezoelectric element is sliced into a large number of vibrators (11) nd the leading ends of the vibrators are embracingly held in positioning holes (33) respectively formed in a top surface of a holding frame (3) and are thus positioned in the outer dimension thereof. Further, a cavity unit (5) is positioned and fixed on the top surface of the holding frame (3).
