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.
