摘要： A piezoelectric component achieves a desired Qm by using a presently available piezoelectric material. The piezoelectric component includes a supporting substrate on which pattern electrodes are provided. Electroconductive supporting members are disposed on the pattern electrodes, and a piezoelectric resonator is mounted on the supporting members. External electrodes of the piezoelectric resonator and the pattern electrodes are electrically connected to each other by the supporting members. Gaps between the piezoelectric resonator and the supporting substrate are filled with a first elastic material element. A second material element may be provided on the surface of the piezoelectric resonator disposed opposite to the surface of the resonator facing the supporting substrate. Only one of these elastic material elements or both these elastic material elements may be used.

The piezoelectric layers are polarized in the longitudinal direction of the base member such that the direction of polarization differs at adjacent piezoelectric layers. At opposite major surfaces of the plurality of piezoelectric layers, internal electrodes are disposed. The internal electrodes have surface areas with different sizes and therefore, areas of pairs of opposing electrodes have different sizes. The internal electrodes are alternately covered by at least two insulating films provided on opposing side surfaces of the base member. The at least two insulating films cover different internal electrodes. External electrodes are disposed on the same or the opposing side surfaces of the base member and the external electrodes are connected to the internal electrodes.
