This proton conductor comprises a complex between phosphoric acid molecules and a coordination polymer wherein metal ions and ligands are linked successively by coordinate bonds. The phosphoric acid molecules include phosphoric acid molecules that are coordinate bonded to a metal ion, and phosphoric acid molecules that are not coordinate bonded to a metal ion. This allows, in the proton conductor comprising the structure containing the phosphoric acid molecules, the ion conductivity to be increased, and further, the stability of the structure to be improved. |
