▎ 摘　　要

NOVELTY - Bio-electrode composition comprises (A) a reaction composite comprising an ionic polymer material and a carbon particle, where the component (A) comprises the carbon particle bonded to the polymer comprising a repeating unit having a structure selected from salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. USE - Bio-electrode composition used in contact with the skin of a living body for detecting physical conditions such as heart rate by an electric signal transmitted from the skin. ADVANTAGE - The bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and which prevents significant reduction in the electric conductivity even when wetted with water or dried. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for manufacturing a bio-electrode having an electro-conductive base material and a living body contact layer formed on the electro-conductive base material, which involves: a. applying the bio-electrode composition onto the electro-conductive base material; and b. curing the bio-electrode composition to form the living body contact layer; 2. a reaction composite comprises the carbon particle bonded to the polymer comprising a repeating unit having a structure selected from ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluoro sulfonamide; 3. a bio-electrode which comprises an electro-conductive base material and a living body contact layer formed on the electro-conductive base material, where the living body contact layer is a cured product of the bio-electrode composition.
