Electronic component and method for manufacturing the same

An electronic component comprising at least one piezoelectric element including:

• a substrate;
• a piezoelectiic material layer supported directly or indirectly by the substrate;
• a first electrode arranged on a principal surface of the piezoelectric material layer;
• a second electrode arranged or the other surface of the piezoelectric material layer;
• wherein the piezoelectric material layer is sandwiched between the first electrode and the second electrode;
• wherein the plezocleotric material layer includes at least a first piezoelectric material area not supported by the substrate and a second piezoelectric material area, other than the first piezoelectric material area, in which the piezoelectric material layer is not supported by the substrate.
• wherein, in the piezoelectric material layer, the second electrode is formed at least on the other surface of the first piezoelectric material area and the second piezoelectric material area;
• wherein, in the piezoelectric material layer, the first electrode Is formed at least on the principal surface of the first piezoelectric material area;
• and
• wherein a part or an entirety of the second plezocleotric material area has a thickness smaller than that of the first plezocleotric material area;
• wherein the substrate does not include an oscillation space, and wherein a multilayer film of an inorganic substance constituting an acoustic mirror is present between the substrate and the second electrode.
