Abstract
A bio-electrode composition contains (A) a silicone bonded to an ionic polymer and having a structure containing a T unit shown by the following general formula (T1): (RSiO) (T1), the structure excluding a cage-like structure. In the formula, Rrepresents a linking group to the ionic polymer. The ionic polymer is a polymer containing a repeating unit having a structure selected from the group consisting of salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. Thus, the present invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity, biocompatibility, stretchability, and adhesion, soft, light-weight, and manufacturable at low cost, and which prevents significant reduction in the electric conductivity even when wetted with water or dried.
