1. A bio-electrode composition comprising:
a resin having a urethane bond and a silicone chain in a main chain; and
an electro-conductive material,
wherein the electro-conductive material is a polymer compound having one or more repeating units selected from the group consisting of fluorosulfonic acid salts shown by the following formula (1)-1, fluorosulfonic acid salts shown by the following formula (1)-2, sulfonimide salts shown by the following formula (1)-3, and sulfonamide salts shown by the following formula (1)-4,

OG Complex Work Unit Chemistry
wherein Rf1 and Rf2 each represent a hydrogen atom, a fluorine atom, a trifluoromethyl group, or an oxygen atom, provided that when Rf1 represents the oxygen atom, Rf2 also represents the oxygen atom to form a carbonyl group together with a carbon atom bonded therewith; Rf3 and Rf4 each represent a hydrogen atom, a fluorine atom, or a trifluoromethyl group, provided that one or more fluorine atoms are contained among the total number of atoms in Rf1 to Rf4; Rf5, Rf6, and Rf7 each represent a fluorine atom, or a linear or branched alkyl group having 1 to 4 carbon atoms, provided that one or more fluorine atoms are contained; X+ represents a sodium ion, a potassium ion, or a cation having an ammonium ion structure shown by the following formula (1)-5; and “m” is an integer of 1 to 4,

OG Complex Work Unit Chemistry
wherein R1 to R4 each represent a hydrogen atom, a linear, branched, or cyclic alkyl group having 1 to 20 carbon atoms, optionally having an ether group, a thiol group, an ester group, a carbonyl group, a sulfonyl group, a cyano group, an amino group, a nitro group, an alkenyl group having 6 to 10 carbon atoms, or a halogen atom, and optionally bonded to each other to form a ring.
