Abstract
An elastic wave element having a piezoelectric substrate equipped with a first main surface, and an excitation electrode arranged on the first main surface and having multiple electrode fingers, wherein, in a cross-sectional view in the direction orthogonal to the first main surface, the width of the electrode fingers at a first height at a distance from the first main surface is greater than the width at a second height located closest to the first main surface.
Claims15
An elastic wave element comprising:
- a piezoelectric substrate comprising a first main surface;
- and
- an excitation electrode comprising a plurality of electrode fingers, the excitation electrode being on the first main surface,
- wherein each of the plurality of electrode fingers is wider at a first height than at a second height in a cross-sectional view in a direction orthogonal to the first main surface, the second height being nearest to the first main surface.
