Abstract
The method for manufacturing an ink jet recording head includes forming an ink pool for supplying ink to a nozzle for jetting ink on a substrate. The method also includes forming, in sequence on the substrate, a diaphragm for pressurizing ink in the ink chamber, a piezoelectric thin film serving as a pressurization source for the diaphragm, and an electrode for the piezoelectric thin film. Patterning of both the piezoelectric thin film and the electrode is done at the same time.
