METHOD FOR MANUFACTURING PIEZOELECTRIC ELEMENT

摘要

There is disclosed a method of manufacturing a piezoelectric element including a step of preparing a green sheet A including a portion which becomes a fired piezoelectric body later by use of a piezoelectric material; a step of joining, to at least one surface of the green sheet A, a green sheet B having an opening in a portion facing the portion which becomes the fired piezoelectric body later, followed by firing to obtain the fired piezoelectric body provided with a reinforcing plate to which the reinforcing plate formed owing to the firing of the green sheet B is attached; and a step of forming a film-like electrode in a portion obtained by the firing of the green sheet A in the fired piezoelectric body provided with the reinforcing plate. According to this method of manufacturing a piezoelectric element, it is possible to obtain the piezoelectric element provided with a thin fired piezoelectric body having a high flatness degree.
