Claim 2:
3. 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 at least one selected from the group consisting of repeating units (2-1) to (2-7) shown in the following general formulas,, , wherein R1, R3, R5, R8, R10, R11, and R13 each independently represent a hydrogen atom or a methyl group; R2, R4, R6, R9, R12, and R14 each independently represent any of a single bond, and a linear, branched, or cyclic hydrocarbon group having 1 to 13 carbon atoms optionally having either or both of an ester group and an ether group; R7 represents a linear or branched alkylene group having 1 to 4 carbon atoms, and one or two hydrogen atoms in R7 are optionally substituted with a fluorine atom; X1, X2, X3, X4, X6, and X7 each independently represent any of a single bond, a phenylene group, a naphthylene group, an ether group, an ester group, and an amide group; X5 represents any of a single bond, an ether group, and an ester group; Y represents an oxygen atom or a —NR19— group; R19 represents a hydrogen atom, or a linear or branched alkyl group having 1 to 4 carbon atoms and optionally bonded to R4 to form a ring; “m” represents an integer of 1 to 4; a1, a2, a3, a4, a5, a6, and a7 satisfy 0≤a1≤1.0, 0≤a2≤1.0, 0≤a3≤1.0, 0≤a4≤1.0, 0≤a5≤1.0, 0≤a6≤1.0, 0≤a71.0, and 0<a1+a2+a3+a4+a5+a6+a7≤1.0; 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; and 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.
