    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 of the present has a substrate 1, an intermediate layer 7 disposed on the substrate 1 and is formed of an insulator, a lower electrode 3 disposed on the intermediate layer 7, a piezoelectric film 4 disposed on the lower electrode 3, and an upper electrode 5 disposed on a position facing the lower electrode 3 with the piezoelectric film 4 interposed therebetween, in which, in a resonant region 8 where the lower electrode 3 and the upper electrode 5 face each other, a space 6 is formed in the substrate 1 and the intermediate layer 7 or between the lower electrode 3 and the intermediate layer 7 and the region of the space 6 is included in the resonant region 8. With the structure, the dissipation of the vibrational energy to the substrate from the resonance portion can be suppressed, thereby improving the quality factor.

    摘要： A filter has a plurality of piezoelectric thin film resonators formed by sandwiching a piezoelectric film with a lower electrode disposed on a substrate and an upper electrode. Each of the piezoelectric thin film resonators has an electrode region formed with the upper electrode and the lower electrode overlapping each other, whose outline includes a curve. Among the plural piezoelectric thin film resonators, the piezoelectric thin film resonators in the opposing electrode regions of the adjacent piezoelectric thin film resonators are shaped to have outlines complementary to each other. With the filter, influences caused by transverse mode undesired wave of the piezoelectric thin film resonators can be suppressed. Therefore, miniaturization can be achieved without sacrificing the mechanical strength of electrodes having hollow structures.

    摘要翻译： 滤波器具有多个压电薄膜谐振器，其通过将设置在基板上的下电极和上电极夹在压电薄膜上而形成。 每个压电薄膜谐振器具有由上电极和下电极形成的电极区域彼此重叠，其轮廓包括曲线。 在多个压电薄膜谐振器中，相邻的压电薄膜谐振器的相对电极区域中的压电薄膜谐振器被成形为具有彼此互补的轮廓。 利用滤波器​​，可以抑制由压电薄膜谐振器的横向不需要的波形引起的影响。 因此，可以在不牺牲具有中空结构的电极的机械强度的情况下实现小型化。
