The present invention has good adhesion to the body of a subject, is less likely to cause discomfort even if it is softly touched for a long time, can maintain stable contact with the body of the subject, and can improve productivity EEG An object is to provide a biological electrode suitable for measurement, and the object has an electrode member that comes into contact with the body of a subject and a conductive support member that supports the electrode member, and at least the electrode member is conductive. Conductive rubber, the conductive rubber includes room temperature curable liquid silicone rubber, agglomerated silver powder and flake silver powder, and the plurality of electrode members protrude from the support member in a brush shape. And the biological electrode used for brain wave measurement.本発明は、被験者の身体への密着性が良好であり、やわらかい肌触りで長時間密着させていても不快感を生じにくく、被験者の身体との安定した接触を維持でき、生産性も向上できる脳波測定に適した生体電極を提供することを課題とし、当該課題は、被験者の身体に接触する電極部材と、前記電極部材を支持する導電性の支持部材とを有し、少なくとも前記電極部材は導電性ゴムからなり、前記導電性ゴムは、室温硬化型の液状シリコーンゴムと、凝集状の銀粉とフレーク状の銀粉とを含んでなり、前記支持部材から複数の前記電極部材がブラシ状に突出するように設けられ、脳波測定に用いられる生体電極により解決される。
