Abstract:
A method of manufacturing an ink jet recording head, comprising the steps of:providing a channel unit including: 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; and an elastic plate, a first surface thereof being bonded onto one surface of the channel forming substrate; providing a resin casing formed with an accommodation space therein; bonding a first face of the casing unit onto a second surface of the elastic plate which is opposite to the first surface; providing a pair of vibrator units, each 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; and inserting the vibrator units into the accommodation space in the casing such that the free ends of the piezoelectric vibrators abut against a second surface of the elastic plate, and such that third faces of the fixation bases which are opposite to the respective first faces are faced with each other.
