PROBLEM TO BE SOLVED: To provide a fibrous piezoelectric element having improved durability capable of taking out an electric output, by a relatively small application stress of rubbing the surface with a finger.SOLUTION: The fibrous piezoelectric element includes a piezoelectric unit where two conductive fibers B obtained by performing electrical conductor coating on fibers and one piezoelectric fiber A are arranged on a substantially same plane, while having contacts. A conductive fiber, a piezoelectric fiber and a conductive fiber are arranged in this order in the piezoelectric unit. The conductive fiber, piezoelectric fiber and conductive fiber are arranged substantially in parallel in the piezoelectric unit.SELECTED DRAWING: Figure 5 |
