    摘要： There is provided a piezoelectric resonator and a piezoelectric thin-film filter including the piezoelectric resonator, the piezoelectric resonator being capable of suppressing long-wavelength spurious modes and short-wavelength spurious modes.
    The planar shape of a vibrating region 18 including a piezoelectric layer 15 disposed between a pair of conductive layers 14 and 16 is rectangle when viewed in the thickness direction. Outer edges 18a of the vibrating region 18 each have a waveform. The vibrating region 18 includes a peripheral portion 18t extending along the outer edges of the planar shape and having a relatively small thickness; and a central portion 18s extending inside the peripheral portion 18t and having a relatively large thickness.

    摘要： A volume wave piezoelectric resonator operating at a predetermined frequency comprises a substrate block (4), a carrier having a plane face (16) and a first thickness e1 and consisting of a first material, a resonant plate (6) having a length L, a width I and a second thickness e2, and consisting of a second piezoelectric material, first and second metal electrodes (12, 14) at least partly covering the resonant plate (6) on each side and least partially facing each other. The resonant plate (6) is fixed perpendicularly in the vicinity of the plane face (16) of the substrate block (4) so ​​that the width of the resonant plate (6) and the first thickness of the substrate block have the same direction, and the first material, the second material, the first thickness of the substrate block, the length, the width I, the second thickness of the resonant plate are configured for trapping volume waves at the operating frequency of the resonator and for producing a plane-to-plane type volume wave piezoelectric resonator, i.e. with volume waves propagating in the direction of the thickness of the resonant plate.

    摘要： A piezoelectric thin-film resonator includes a substrate (10), a lower electrode (12) provided on the substrate (10), a piezoelectric film (14) provided on the lower electrode (12), and an upper electrode (16) provided on the piezoelectric film (14) so as to have a portion that overlaps the lower electrode (12) across the piezoelectric film (14). At least a part of an outer end of the piezoelectric film (14) is further in than an outer end of an opposing region in which the upper and lower electrodes overlap each other across the piezoelectric film (14).
