ABSTRACT:
An ink jet recording head for ejecting ink drops by expanding or shrinking a pressure generation chamber of an ink flow route forming member consisting of nozzle openings, the pressure generation chamber, an ink supply port, and a reservoir. Piezoelectric vibrators are disposed and fixed in a row with a predetermined pitch, to a piezoelectric vibrator support plate having excellent cutting properties and the piezoelectric vibrator support plate is fixed to a base made of material having a larger rigidity than the support plate. If the piezoelectric vibrator support plate receives reaction forces when ink is ejected, the base having a larger rigidity than the support plate resists the reaction force and suppresses undesired displacement of the contiguous piezoelectric vibrators.
