摘要： A diaphragm structure includes a ceramic substrate having at least one window portion and a thin diaphragm laminated onto the ceramic substrate so as to cover the window portion, wherein only a part of an interface between the ceramic substrate and the thin diaphragm is joined to form a joint of the diaphragm. A diaphragm structure is free from instability caused by a breakage or deformation of a partition wall between window portions upon punching or laminating even if a diaphragm structure employs a design in which dimensions of a diaphragm portion is maintained and simultaneously a distance between diaphragm portions is made narrow to restrain a surface area excluding a diaphragm portion of a diaphragm structure or a design in which a plurality of diaphragm portion having various configurations and dimensions are disposed.

摘要： A piezoelectric and/or electrostrictive film-type element comprises a zirconia substrate with a thin-walled diaphragm section provided integrally to cover and close a window to serve as a hollow space, and a film-shaped piezoelectric and/or electrostrictive operating section composed of a lower electrode, a piezoelectric and/or electrostrictive layer, and an upper electrode which are successively provided in a layered configuration on an outer surface of the diaphragm section in accordance with a film-forming method, wherein at least a part of a peripheral edge portion of the piezoelectric and/or electrostrictive layer extends laterally beyond a corresponding peripheral edge portion of the lower electrode to construct an overhang section located opposingly over the diaphragm section, and the overhang section is in a state of incomplete connection with respect to a partial region of the diaphragm section located just under by the aid of particles of an alumina-magnesia compound such as spinel particles allowed to intervene therebetween. Thus, it is possible to effectively improve, for example, the piezoelectric and/or electrostrictive characteristics such as the displacement amount, and the resonance frequency characteristics.
