摘要： TO reduce frequency variations caused by a change in frequency constant and suppress unnecessary vibrations in the case where the frequency constant of apiezoelectric substrate has a gradient. A piezoelectric resonator has vibrating electrodes 4 and 5 facing each other, which are formed on two major surfaces of apiezoelectric substrate Ia, and trapped vibrations are generated between the two vibrating electrodes. The piezoelectric substrate Ia has a constant thickness. The frequency constant of the piezoelectric substrate Ia has a gradient in a surface direction. The vibrating electrodes 4 and 5 are formed to have a gradient thickness so that the thickness gradually increases as the frequency constant of the piezoelectric substrate increases. By forming the vibrating electrodes to have a gradient thickness, unnecessary in-band vibrations are suppressed, and frequency variations are reduced.

摘要： A piezoelectric resonator includes a pair of driving electrodes and a pair of lead electrodes that are formed facing each other on the frontside and backside of a piezoelectric plate that operates in a thickness-shear vibration mode. The front and back driving electrodes are formed such that they each have one or more pairs of parallel sides and have the same shape, and their centers face each other. The parallel sides of one of the front and back driving electrodes are formed parallel with either the X-axis or the Z′-axis of the piezoelectric plate, but the parallel sides of the other driving electrodes are formed without being parallel with the X-axis and Z′-axis thereof.

摘要： An object of the present invention is to provide a piezoelectric thin film device including a single or a plurality of film bulk acoustic resonators wherein a frequency impedance characteristic is unsusceptible to spuriousness. In a film bulk acoustic resonator, a piezoelectric thin film is supported by a support substrate via an adhesive layer. An upper electrode and a lower electrode each having a predetermined pattern are formed on upper and lower surfaces of the piezoelectric thin film. Further, on the upper surface of the piezoelectric thin film, an additional film for adding a mass to an outside of an excitation region is formed as superposed on the upper electrode.
