Beschreibung
Zusammenfassung:	A piezoelectric unit includes a diaphragm made of ceramics, a base portion having a pressure chamber in which the diaphragm is set to a wall and a piezoelectric element having a dielectric layer provided at the opposite side of the base portion with respect to the diaphragm. In the piezoelectric unit, the roughness of a crystal of the outermost interface at the side of the piezoelectric element of the diaphragm is further smoothened than that of a ceramics material which is included in the diaphragm more inside than the interface.
