Disclosed is a modified electroconductive polymer material, which comprises a metal filled in a space between the chains of an electroconductive polymer. The metal is oxidized (partially formed as a hydroxide) through a chemical reaction between three substances consisting of the metal, a cation radical/dication, and absorbed water.
