PURPOSE: To obtain high energy density, low self-discharge and high coulomb efficiency by making a positive electrode of polypyrrole while making a negative electrode of acetylene high polymer and a solvent of electrolyte of an ether system compound.
CONSTITUTION: Polypyrrole to be used as a positive electrode 5 can be a single polymer of pyrrole while being able to be a copolymer with the other compounds able to be polymerized. The kinds of acetylene high polymers to be used as a negative electrode 3 are not particularly limited and, for instance, an acetylene high polymer or the like to be obtained in a filmy state at the time of polymerization is used. Further, as an ether system compound to be used for a solvent of an electrolyte the aliphatic family, alicyclic type and aromatic family ether system compounds are used.
