Bio-Electrode, And Method For Manufacturing The Same

The present invention is a bio-electrode including: a substrate having anti-reflective structure for light on at least one side; and (A) an electro-conductive layer having electro-conductive wiring on the opposite side from the side having the anti-reflective structure of the substrate. This provides: a bio-electrode that allows thin, highly transparent, highly sensitive to biological signals, excellent in biocompatibility, light-weight, manufacturable at low cost, capable of preventing significant reduction in sensitivity to biological signals even when attached on the skin for a long time and when wetted with water or dried, and comfortable without itching, reddening, nor rash of the skin.
