ABSTRACT:
An ink jet recording head having high printing quality which is achieved independently of ambient temperature changes. An overhang portion (22) is formed on a surface of a frame (20) in such a manner that the overhang portion extends close to an island portion (9) of a resilient plate. A front end (17) of a fixed board (14) is fixed to the overhang portion (22) so that a gap (23) is interposed between a lateral side of the fixed board (14) and the frame (20). The piezoelectric vibration elements (8) are secured to the opposite end of the fixed board and abut against each of the island portions. The thickness (L0) of the overhang portion (22) affects that thermal expansion differential derived from a difference in the materials of the frame (20) and the piezoelectric vibration element. Since the thickness is minimized, the thermal expansion differential between the frame (20) and the piezoelectric vibration elements (8) is correspondingly minimized.
