The present invention provides a fibrous piezoelectric element device capable of adding a sensor function later without restricting movement and texture. SOLUTION: A core portion 3 made of conductive fiber and a sheath portion 2 made of braided piezoelectric fiber so as to cover the core portion 3, the piezoelectric fiber being a main component As shown, braided piezoelectric elements 1 including polylactic acid, and the wrapping angle of the piezoelectric fibers with respect to the conductive fibers is 15 ° or more and 75 ° or less, and the conductive fibers 8 and the insulating fibers 7 are alternately arranged. To the fibrous structure. [Selection] Figure 2 |
