An ink jet recording head including: a vibrating plate made of ceramic; a pressure producing chamber forming member, made of ceramic, for forming a plurality of pressure producing chambers in rows; and drive electrodes formed on a surface of the vibrating plate so as to confront the pressure producing chambers. A width of the drive electrode is smaller than a width of the pressure producing chamber. A width of a piezoelectric vibrating element is larger than the width W2 of the drive electrode and smaller than the width of the pressure producing chamber, so that the operation region of the piezoelectric vibrating element is regulated by the width of the drive electrode and the peripheral portions of the piezoelectric vibrating element are bonded to the peripheral portions of the drive electrode reliably. |
