The present invention provides a bio-electrode composition including a silicone bonded to a fluorosulfonic acid salt, wherein the fluorosulfonic acid salt is shown by the following general formula (1): n n n n n n n n n n wherein R 1 represents an alkylene groups with 1 to 20 carbon atoms or an arylene groups with 6 to 10 carbon atoms; Rf 1 and Rf 2 each represent a hydrogen atom, a fluorine atom, an oxygen atom, or a trifluoromethyl group; Rf 3 and Rf 4 each represent a hydrogen atom, a fluorine atom, or a trifluoromethyl group, provided that one or more fluorine atoms are contained in Rf 1 to Rf 4 ; M is selected from sodium, potassium, and silver. This can form a living body contact layer for a bio-electrode that is excellent in electric conductivity and biocompatibility, light-weight, manufacturable at low cost, and free from large lowering of the electric conductivity even though it is wetted with water or dried. |
