    摘要: A bio-electrode including an electro-conductive base material and a living body contact layer formed on the electro-conductive base material, where the living body contact layer includes an electro-conductive polymer composite including a component A: a π-conjugated polymer and a component B: a dopant polymer, and the component B dopant polymer contains a repeating unit having any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide and has a weight-average molecular weight of 1,000 to 500,000. This provides: a bio-electrode that is a thin film of high transparency, has high sensitivity to biological signals, has excellent biocompatibility, is light-weight, can be manufactured at low cost, can control significant reduction in sensitivity to biological signals either when soaked in water, dried, or attached to the skin for a long time, causes no itchiness, red spots, rashes, etc. of the skin, and is comfortable; a bio-electrode composition; and a method for manufacturing a bio-electrode.
