    摘要： A filter includes multiple piezoelectric thin-film resonators each having a substrate, a lower electrode formed on the substrate, a piezoelectric film formed on the lower electrode, and an upper electrode provided on the piezoelectric film so that the upper electrode and the lower electrode face each other across the piezoelectric film. The multiple piezoelectric thin-film resonators include a first resonator in which at least a part of an outer curved portion of the piezoelectric film of the first resonator is located further out than an outer curved portion of a region in which the upper electrode and the lower electrode face each other across the piezoelectric film. The multiple piezoelectric thin-film resonators includes a second resonator in which at least a part of an outer curved portion of the piezoelectric film of the second resonator substantially coincides with an outer curved portion of a region in which the upper electrode and the lower electrode face each other across the piezoelectric film or is further in than the outer curved portion of the region.

    摘要： A piezoelectric thin film resonator includes a substrate, a lower electrode formed on the substrate, a piezoelectric film formed on the substrate and the lower electrode, and an upper electrode formed on the piezoelectric film and opposing the lower electrode, an upper electrode formed on the piezoelectric film. The upper electrode has a main portion and an extended portion connected to the main portion, the main portion opposing the lower electrode and an opening disposed between the substrate and the lower electrode, the extended portion having a portion which opposes the opening and the substrate.
