ABSTRACT:
The method manufactures a liquid ejection head in which piezoelectric bodies are formed on a diaphragm which constitutes walls of a plurality of pressure chambers. The method comprises the steps of: filling piezoelectric material into a plurality of recess sections of a molding substrate formed with the plurality of recess sections so as to correspond to the pressure chambers; then performing a lamination step of arranging a first green sheet that is to form the diaphragm onto the molding substrate in such a manner that the first green sheet covers the recess sections filled with the piezoelectric material; then performing a first heating step of heating the piezoelectric material filled in the recess sections; and then separating the piezoelectric material from the molding substrate.
