Abstract: [Object] To provide a transducer capable of providing a high degree of freedom in deformation and suppressing a risk of breakage and a method of producing the transducer. [Solving Means] In order to achieve the above-described object, a transducer according to an embodiment of the present technology includes an elastomer. The elastomer extends along a predetermined axis direction, and has both end portions in which at least two electrodes having followability are disposed on both sides around a predetermined axis in the predetermined axis direction, the both end portions being elongated to be folded in a direction perpendicular to the predetermined axis. This makes it possible to provide a high degree of freedom in deformation and to suppress a risk of breakage.
