    • A thin-film piezoelectric resonator includes a substrate, and first and second excitation portions. The substrate includes first and second cavities. The first excitation portion is disposed over the first cavity, and includes a first electrode, a first piezoelectric material and a second electrode laminated successively. An overlapping region among the first electrode, the first piezoelectric material and the second electrode defines a contour of a periphery of the first excitation portion. A first distance is defined as a distance from an end of the first excitation portion to an opening end of the first cavity. The second excitation portion is disposed over the second cavity, and includes a third electrode, a second piezoelectric material and a fourth electrode laminated successively. A second distance is defined as a distance from an end of the second excitation portion to an opening end of the second cavity and different from the first distance.
