Abstract:
An ink jet recording head, comprising:a channel forming substrate, in which a channel which extends from a common ink reservoir to nozzle orifices via pressure chambers associated with the respective nozzle orifices, an elastic plate, a first surface thereof being bonded onto one surface of the channel forming substrate; a supporting base formed with at least one through hole therein, a first face thereof being bonded onto a second surface of the elastic plate which is opposite to the first surface of the elastic plate; a resin casing formed with an accommodation space therein, a first face thereof being bonded onto a second face of the supporting base which is opposite to the first face of the supporting base; and at least one vibrator unit, including a fixation base, and piezoelectric vibrators arranged on a first face of the fixation base such that first ends of the piezoelectric vibrators are fixed thereon and opposite free ends overhang a second face of the fixation base, the vibrator unit accommodated in the accommodation space of the casing such that the piezoelectric vibrators extend through the through hole of the supporting base and the free ends thereof abut against the second surface of the elastic plate, and such that the second face of the fixation base is bonded onto the second face of the supporting base.
