A dielectric transducer for use in a sensor, actuator or generator comprising a plurality of layers of transducer foils, wherein an electrically contactable and conductive layer forming an electrode layer is applied to at least one side of each transducer foil. Expediently, at least two contact elements are provided, each of which is arranged at least partially in a recess or in a through-channel and extends over at least one layer of transducer foils, adjacent electrode layers being electrically conductively connected to different contact elements. Since adjacent electrode layers are connected to different contact elements, intended use is possible, and bringing together several contact lines is advantageously not necessary. Furthermore, the invention relates to a method for producing a multilayer dielectric transducer for use in a sensor, an actuator or a generator, as well as an actuator, a sensor or a generator.

[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.
