Patent ID: 6862783

Claim:
A manufacturing method for an ink jet recording head configured so that ink can be discharged from nozzles provided in a plurality of pressure chambers by applying voltage to a plurality of piezoelectric elements to induce volumetric changes therein, comprising: a peeling layer formation process for forming a peeling layer for producing peeling by irradiation of light onto a first base plate exhibiting light transmissivity; a common electrode layer formation process for forming a common electrode film on said peeling layer; a piezoelectric element formation process for forming said plurality of piezoelectric elements on said common electrode film; an adhesive joining process for adhesively joining a second base plate, through an adhesive layer, to a surface whereon said piezoelectric elements are formed; a first peeling process for causing peeling in said peeling layer by irradiating said peeling layer from a first base plate side thereof with prescribed light, thereby peeling away said first base plate; a bonding process for bonding a pressure chamber plate provided with said plurality of pressure chambers onto said common electrode film from which said first base plate has been peeled, so as to seal said pressure chambers; and a second peeling process for peeling away said second base plate.
