    • A piezoelectric thin film device (10) comprising a substrate (12) having a vibration space (20), and a piezoelectric lamination structure (14) formed on the upper surface of the substrate, the piezoelectric lamination structure comprising a piezoelectric film (16) and a lower electrode (15) and upper electrode (17) which are formed on opposite surfaces thereof, respectively, the vibration space (20) being so formed as to allow the vibration of a vibrating section (23) constituted by including at least part of the piezoelectric lamination structure (14) and part of an insulating layer (13). The vibrating space (20) is composed of a first via hole (21) formed from the lower surface of the substrate (12) toward the upper surface thereof so as to form an intermediate surface (25) in the substrate, and a second via hole (22) formed from the intermediate surface (23) toward the upper surface of the substrate so as to be positioned inside the first via hole (21) as seen vertically.
    • 一种压电薄膜器件(10),包括具有振动空间(20)的衬底(12)和形成在所述衬底的上表面上的压电层压结构(14),所述压电层压结构包括压电薄膜(16) 以及分别形成在其相对表面上的下电极(15)和上电极(17),所述振动空间(20)形成为允许振动部分(23)的振动,所述振动部分(23)包括至少部分 的压电层压结构(14)和绝缘层(13)的一部分。 所述振动空间(20)由从所述基板(12)的下表面向其上表面形成的第一通孔(21)构成,以在所述基板上形成中间面(25),所述第二通孔 从中间表面(23)形成的孔(22)朝向基板的上表面,以便位于第一通孔(21)的内部。
