Claim 1:
2. The bio-electrode composition according to claim 1, wherein
the repeating unit having a structure selected from the group consisting of salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide comprises a structure shown by any of the following general formulae (1)-1 to (1)-4,, , wherein Rf1 and Rf2 each represent a hydrogen atom, a fluorine atom, an oxygen atom, a methyl group, or a trifluoromethyl group, provided that when Rf1 and Rf2 represent an oxygen atom, the single oxygen atom represented by Rf1 and Rf2 bonds to a single carbon atom to form a carbonyl group; Rf3 and Rf4 each represent a hydrogen atom, a fluorine atom, or a trifluoromethyl group, provided that at least one of Rf1 to Rf4 is a fluorine atom or a trifluoromethyl group; Rf5, Rf6, and Rf7 each represent a fluorine atom, or a linear or branched alkyl group having 1 to 4 carbon atoms, and have at least one fluorine atom; “m” represents an integer of 1 to 4; and M+ represents an ion selected from the group consisting of an ammonium ion, a lithium ion, a sodium ion, a potassium ion, and a silver ion.
