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 (A) ionic material and a (B) resin other than the component (A), in which the component (A) has both a repeating unit “a” of a lithium salt, a sodium salt, a potassium salt, or an ammonium salt of sulfonamide including a partial structure represented by the following general formula (1) and a repeating unit “b” having a silicon atom,n n—R 1 —C(═O)—N − —SO 2 —Rf 1 M + (1). |
