<p>PROBLEM TO BE SOLVED: To provide a piezoelectric sensor capable of performing position detection and load detection within the piezoelectric sensor.SOLUTION: A piezoelectric sensor 10 has a piezoelectric layer held between an upper electrode 12 and a lower electrode 13. The upper electrode 12 has a plurality of first pattern electrodes 14 extending in one direction. The lower electrode 13 has a plurality of second pattern electrodes 15 extending in the other direction intersecting the one direction. A load is measured from a generated electric charge amount, and a position is determined from an electrode generating the charge.</p> |
