Abstract
A bio-electrode composition contains (A) an ionic polymer material, (B) an addition reaction-curable silicone having at least a hydrosilyl group, (C) a platinum-group catalyst, and a solvent. The bio-electrode composition has a water content of 0.2 mass % or less. The solvent includes one or more of an ether solvent, an ester solvent, and a ketone solvent each of which does not contain a hydroxy group, a carboxyl group, a nitrogen atom, or a thiol group. Thus, 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 and biocompatibility, light-weight, and manufacturable at low cost, and which does not leave residue on skin after attachment to and peeling from the skin; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.
