Claim 3:
4. The bio-electrode according to claim 1, wherein in the bio-electrode composition, the repeating unit-a is at least one repeating unit selected from repeating units shown by the following general formulae (2),, wherein R1, R3, R5, R8, R10, R11, and R13 each independently represent a hydrogen atom or a methyl group; R2, R4, R6, R9, and R12 each independently represent any of a single bond, an ester group, or a linear, branched, or cyclic hydrocarbon group having 1 to 13 carbon atoms, optionally having either or both of an ether group and an ester group; R7 represents a linear or branched alkylene group having 1 to 4 carbon atoms, and one or two of the hydrogen atoms in R7 are optionally replaced with a fluorine atom; X1, X2, X3, X4, and X6 each independently represent any of a single bond, a phenylene group, a naphthylene group, an ether group, an ester group, or an amide group; X5 represents any of a single bond, an ether group, or an ester group; X7 represents a single bond, an arylene group having 6 to 12 carbon atoms, or —C(═O)—O—X10—; X10 represents a linear, branched, or cyclic alkylene group having 1 to 12 carbon atoms, or a divalent aromatic hydrocarbon group having 6 to 10 carbon atoms, optionally having an ether group, a carbonyl group, or an ester group in X10; Y represents an oxygen atom or an —NR19— group, optionally bonded to R4 to form a ring; R19 represents a hydrogen atom, or a linear or branched alkyl group having 1 to 4 carbon atoms; “m” is an integer of 1 to 4; a1, a2, a3, a4, a5, a6, and a7 are numbers defined in terms of mole fractions satisfying 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≤a7<1.0, and 0<a1+a2+a3+a4+a5+a6+a7<1.0; and M+ is an ion selected from the group consisting of an ammonium ion, a sodium ion, a potassium ion, and a silver ion.
