ABSTRACT:
This ink jet recording head manufacturing method comprises (A) a process for forming a peeling layer11wherein peeling is induced by light irradiation, on a base plate10exhibiting light-transmissivity, (B) a process for forming a common electrode film3on the peeling layer11, (C) a process for forming a plurality of piezoelectric elements4, (D) a process for forming a reservoir piece5comprising a lid structure that accommodates in its interior one or more piezoelectric elements4, which interior forms an ink reservoir51, (E) a process for irradiating the peeling layer11with prescribed light from the base plate10side thereof, thereby producing peeling in the peeling layer11, and peeling the base plate10away, and (F) a process for bonding a pressure chamber plate2, whereon are provided a plurality of pressure chambers21, to the common electrode film3separated from the base plate, so that the pressure chambers21are sealed.Heads compatible with high resolution can thus be manufactured because thin pressure chamber plates can be fabricated in a separate process from the piezoelectric element formation process and then, last of all, bonded in place.
