Abstract
A pressing sensor includes a piezoelectric film and first and second detection electrodes. The piezoelectric film has a chiral polymer drawn at least in a uniaxial direction, and has a first main surface and a second main surface. The first and second detection electrodes are arranged on at least one of the first and second main surfaces. The first and second detection electrodes are arranged so as to face each other obliquely to the uniaxial direction.
