Abstract
The present invention provides a flexible conductive crosslinked body excellent in durability having a small influence of a reaction residue after the crosslinking on an object to which the conductive crosslinked body adheres, and a production process of the flexible conductive crosslinked body. The conductive crosslinked body is synthesized from a conductive composition containing a rubber polymer, an organic metal compound, and a conducting agent and has a crosslinked structure. The production process of the conductive crosslinked body includes: a mixed solution preparing step for preparing a mixed solution in which the rubber polymer, the conducting agent, and the organic metal compound are mixed in a solvent capable of dissolving the rubber polymer and capable of chelating the organic metal compound; and a crosslinking step for removing the solvent from the mixed solution to allow a crosslinking reaction to proceed. The conductive crosslinked body is suitable as an electrode or a wire for a transducer, a wire for a flexible wiring board, and an electromagnetic wave shield.
