Abstract
A bulk acoustic wave resonant structure and a preparation method therefor, and an acoustic wave device are provided. The bulk acoustic wave resonant structure includes: a substrate; a reflection structure, a first electrode, a piezoelectric layer and a second electrode, which are successively located on the substrate, wherein the first electrode comprises a first sub-electrode located in a first region and a second sub-electrode located in a second region other than the first region, and the piezoelectric layer respectively comes into direct contact with the first sub-electrode and the second electrode in the first region; and a first gap, which is located between the piezoelectric layer and the second sub-electrode, wherein an orthographic projection of the first gap on the substrate surrounds the first region.
