Abstract
A pressure sensor for use in a folding structure that includes a foldable piezoelectric film, a first electrode disposed on a first main surface of the piezoelectric film, a plurality of second electrodes disposed side by side on a second main surface of the piezoelectric film so as to face the first electrode and to be positioned along a direction orthogonal to a folding line of the piezoelectric film, a folding detection unit that detects a folded state of the piezoelectric film, and a processing unit that changes processing of at least one of signals generated on the second electrode when the piezoelectric film receives a pressing operation and the folding detection unit is detecting the folded state of the piezoelectric film.
