The present invention relates to an ink jet recording head wherein the movement of a piezoelectric element (1) moves part of an ink flow passage substrate (5) so as to jet out ink stored therein in the form of ink droplets. This ink jet recording head comprises: a fixing plate (2), a plurality of piezoelectric vibrators (11) obtainable by cutting and dividing said plage-shaped piezoelectric element (1) while said piezoelectric element is fixed on said fixing plate (2), holding means (3) for positioning and holding at least one of said piezoelectric vibrators (11) and said fixing plate (2) in a direction perpendicular to the displacement direction of said piezoelectric vibrators (11), and an ink flow passage substrate (5) mounted on said holding means (3) and including a nozzle plate (6), an ink flow passage forming plate (7) and an elastic plate (8).
