METHOD OF MANUFACTURING ELECTROMECHANICAL TRANSDUCER ELEMENT, ELECTROMECHANICAL TRANSDUCER ELEMENT, DISCHARGING HEAD, AND INKJET RECORDING DEVICE

摘要

Disclosed is a method of manufacturing an electromechanical transducer element including a first process of hydrophobizing a first area of an electrode by forming a self-assembled monolayer film; a second process of applying a sol-gel solution onto a predetermined second area of the electrode so as to produce a complex oxide; a third process of producing the complex oxide by calcining the electrode; a fourth process of acid-washing the electrode on which the complex oxide has been produced; a fifth process of hydrophobizing the first area of the acid-washed electrode by forming the self-assembled monolayer film; a sixth process of applying the sol-gel solution onto the predetermined second area; and a seventh process of producing the complex oxide by calcining the electrode.
