The present invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode that is excellent in conductivity and biocompatibility, is light-weight, can be manufactured at low cost, and can control significant reduction in conductivity even though the bio-electrode is soaked in water or dried. The present invention is accomplished by a bio-electrode composition including an ionic material and a resin, in which the ionic material is a lithium salt, a sodium salt, a potassium salt, a calcium salt, or an ammonium salt of sulphonamide represented by the following general formula (1).
[R1—C(═O)—N−—SO2—Rf1]nMn+ (1)
