ABSTRACT:
A method is provided for manufacturing an ink jet recording head including a reservoir to which ink is supplied from outside, a pressure generating chamber leading to the reservoir, and a nozzle orifice leading to the pressure generating chamber. According to the method, the ink jet recoding head is fabricated by conducting semiconductor processes such as a film forming step, a photolithography step, an etching step and the like, on a single substrate. Thus, there is no need for multiple substrates or adhesives.
