SURFACE ACOUSTIC WAVE DEVICE |
| 摘要 |
A surface acoustic wave device includes a piezoelectric substrate, an IDT electrode that is provided on the piezoelectric substrate and includes combtooth-shaped electrode fingers, and a wiring electrode that is connected to the IDT electrode. A line width of the electrode fingers at a lower edge thereof and a line width of the electrode fingers at an upper edge thereof in a cross section of the electrode fingers that is perpendicular or substantially perpendicular to a longitudinal direction of the electrode fingers is smaller than a maximum line width of the electrode fingers. |
