Document Type and Number:
WIPO Patent Application WO/2024/009727
Kind Code:
A1
Abstract:
This sensor comprises: a piezoelectric film having a first main surface and a second main surface; a first electrode disposed on the first main surface; a second electrode disposed on the second main surface; and a wiring section. The first electrode and the second electrode, when viewed in a first direction, overlap each other, and each include a first portion that overlaps with the piezoelectric film. Also, when viewed in the first direction, the first electrode and the second electrode overlap each other, and each include a second portion that does not overlap with the piezoelectric film. The first portion and the second portion are arranged side-by-side in a second direction orthogonal to the first direction. The wiring section, when viewed in the first direction, overlaps with the second portion, and includes: a wiring board having a third main surface and a fourth main surface; a first conductor disposed on the third main surface and electrically connected to the first electrode; and a second conductor disposed on the fourth main surface and electrically connected to the second electrode.
