Abstract
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): wherein Rrepresents an alkylene groups with 1 to 20 carbon atoms or an arylene groups with 6 to 10 carbon atoms; Rfand Rfeach represent a hydrogen atom, a fluorine atom, an oxygen atom, or a trifluoromethyl group; Rfand Rfeach represent a hydrogen atom, a fluorine atom, or a trifluoromethyl group, provided that one or more fluorine atoms are contained in Rfto Rf; 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.
