A dielectric film which has high electrical resistance and excellent durability and a process for producing the dielectric film are provided. Also provided is a transducer which has large displacement and excellent durability. The dielectric film includes a three-dimensional crosslinked body that is synthesized from an organic metal compound, a rubber polymer that is other than a polydimethyl siloxane and has a functional group that is reactive with the organic metal compound, and an inorganic filler that has a functional group that is reactive with the organic metal compound. The transducer is configured by interposing the dielectric film between at least a pair of electrodes. The dielectric film may be produced by preparing a first solution that contains a rubber polymer and an inorganic filler in a solvent that is capable of dissolving the rubber polymer and of chelating an organic metal compound, then preparing a second solution by mixing the organic metal compound into the first solution, and then removing the solvent from the second solution to allow a crosslinking reaction to proceed.

A flexible conductive material includes an elastomer, a conductive agent filled in the elastomer, and an adsorbent fixed inside the elastomer and able to adsorb ionic material. With the flexible conductive material, ionized impurities are unlikely to transfer to an adherend such as a dielectric film. Thus, leakage current during application of voltage decreases. Accordingly, by forming an electrode and a wiring with the flexible conductive material, leakage current can be reduced, and a transducer and a flexible wiring board having excellent durability can be produced. In addition, using the flexible conductive material, an electromagnetic shield can be produced having a small leakage current.
