Claim 3:
4. The bio-electrode composition according to claim 2, wherein the ionic polymer material (A) comprises an ammonium ion shown by the following general formula (3) as the M+,, wherein R101d, R101e, R101f, and R101g each represent a hydrogen atom, a linear, branched, or cyclic alkyl group having 1 to 12 carbon atoms, a linear, branched, or cyclic alkenyl group or alkynyl group having 2 to 12 carbon atoms, or an aromatic group having 4 to 20 carbon atoms, and optionally have one or more selected from the group consisting of an ether group, a carbonyl group, an ester group, a hydroxy group, an amino group, a nitro group, a sulfonyl group, a sulfinyl group, a halogen atom, and a sulfur atom; and R101d and R101e, or R101d, R101e, and R101f, are optionally bonded to each other together with a nitrogen atom bonded therewith to form a ring in which R101d and R101e, or R101d, R101e, and R101f, represent an alkylene group having 3 to 10 carbon atoms, or to form a heteroaromatic ring having the nitrogen atom in the formula (3) within the ring.
