Abstract
The present invention provides a bio-electrode composition including: a resin containing a urethane bond in a main chain and a silsesquioxane in a side chain; and an electro-conductive material, wherein the electro-conductive material is a polymer compound having one or more repeating units selected from fluorosulfonic acid salts shown by the following general formulae (1)-1 and (1)-2, sulfonimide salts shown by the following general formula (1)-3, and sulfonamide salts shown by the following general formula (1)-4. This can form a living body contact layer for a bio-electrode that is excellent in electric conductivity and biocompatibility, light in weight, manufacturable at low cost, and free from large lowering of the electric conductivity even when it is wetted with water or dried. The present invention also provides a bio-electrode in which the living body contact layer is formed from the bio-electrode composition, and a method for manufacturing the bio-electrode.
