Abstract
The present invention is a bio-electrode composition containing: an electro-conductive polymer composite including (A) a π-conjugated polymer and (B) a dopant polymer containing a repeating unit-a1 having a hydroxy group and/or a carboxy group and a repeating unit-a2 having a sulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide, the dopant polymer having a weight-average molecular weight of 1,000 to 500,000; and (C) a crosslinking agent. This provides: a bio-electrode composition that allows 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 when soaked in water for a long time or when attached to the skin for a long time, causes no itchiness, red spots, rashes, etc. of the skin, and is comfortable; a bio-electrode; and a method for manufacturing a bio-electrode.
