PROBLEM TO BE SOLVED: To provide an organic electrode for reducing the quantity of carbon fibers while retaining the performance of the organic electrode as a lead wire.SOLUTION: An organic electrode comprises an electrode portion, and a lead wire connected electrically with the electrode portion. The lead wire includes: a carbon fiber bundle extending in the extending direction of the lead wire a reinforcing member extending in the extending direction of the lead wire for reinforcing the carbon fiber bundle and a coating portion for coating the carbon fiber bundle and the reinforcing member. The carbon fiber bundle has an electric resistance equal to or less than 3 Ω per 1 cm, and the reinforcing member has an X-ray transmission.COPYRIGHT: (C)2014,JPO&INPIT【課題】生体電極のリード線としての性能を確保しつつ、炭素繊維の量を減らすことを目的とする。【解決手段】生体電極は、電極部と、電極部と電気的に接続されたリード線と、を備える生体電極であって、リード線は、リード線の延在方向に延びる炭素繊維束と、リード線の延在方向に延び、炭素繊維束を補強する補強材と、炭素繊維束、及び補強材を覆う被覆部と、を備え、炭素繊維束は、1cm当たり3Ω以下の電気抵抗を有し、補強材は、X線透過性を有する。【選択図】図3
