Title: PRESSURE DETECTION DEVICE AND INPUT DEVICE
Abstract:
[Problem] To provide a piezoelectric sensor which is capable of location detection and load detection inside the piezoelectric sensor. [Solution] A piezoelectric sensor (10) of the present invention is configured to comprise: a piezoelectric layer (11) that generates an electric charge when pressed by an input means; a first electrode (12) that is arranged on a first main surface of the piezoelectric layer; a second electrode (13) that is arranged on a second main surface of the piezoelectric layer (11), said second main surface being on the reverse side of the first main surface; a first capacitor (C1) or a first resonant circuit (RC1) that is connected to the first electrode (12); and a first detection unit (20) that is connected to the first electrode (12).
