Abstract
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.

A process for forming an ink jet recording head wherein the movement of a piezoelectric element moves part of an ink flow passage substrate so as to jet out ink stored therein, said process comprising the steps of:
- attaching a plate shaped piezoelectric element to a fixing plate;
- cutting said piezoelectric element into a plurality of piezoelectric vibrators;
- mounting an ink flow passage substrate on a holding device;
- inserting said piezoelectric vibrators, mounted on said fixing plate, into said holding device so as to allow said piezoelectric vibrators and said ink flow passage substrate to be brought into contact therebetween;
- engaging a vibrator positioning member with said ink flow passage substrate and said holding device so as to regulate the relative position thereof.

A process for forming an ink jet recording head wherein movement of a piezoelectric element moves part of an ink flow passage substrate so as to jet out ink stored therein, said process comprising the steps of:
- arranging a front edge of a plate-shaped piezoelectric element so as to project a distance which corresponds to leading ends of two positioning portions provided on the two sides of a fixing plate;
- bonding said piezoelectric element and said fixing plate to each other;
- and
- cutting and dividing said piezoelectric element into a large number of vibrators so that leading ends of said respective vibrators are matched to said positioning portions with accuracy.
