PROBLEM TO BE SOLVED: To provide a bioelectric signal detection electrode which permits a subject of measurement to put on without a feeling of incongruity and is free from deterioration due to a secular change.SOLUTION: A spongy conducting fiber having a prescribed thickness (10 mm for example) is formed as a body portion 11, and the lower side of the body portion 11 where the conducting fiber is dense is formed as a living body contacting side 12 to contact the skin surface of the living body. The top side of the body portion 11 where the conducting fiber is dense is formed as a signal outputting side 13 to output the electric signal of the living body. Furthermore, an approaching part 14 having electric resistance lower than the body portion 11 and designed to electrically connect the living body contacting surface 12 and the signal outputting surface 13 is formed. The approaching part 14 is a part where a part of the signal outputting surface 13 is brought closer to the living body contacting surface 12 so as to make it have a prescribed space (2 mm for example) with respect to the living body contacting surface. For example, it can be formed by contracting the spongy conducting fiber of the body portion 11 by heat treatment.COPYRIGHT: (C)2010,JPO&INPIT【課題】被計測者が違和感なく装着することができ、経年変化による劣化のない生体電気信号検出電極を提供する。【解決手段】所定の厚さ(例えば、10mm)のスポンジ状の導電性繊維を本体部11とし、本体部11の下面で導電性繊維が密集している面を、生体の皮膚表面に接触するための生体接触面12とする。本体部11の上面で、導電性繊維が密集している面を、生体の電気信号を出力するための信号出力面13とする。更に、本体部11よりも低い電気抵抗で、生体接触面12と信号出力面13の間を電気的に接続するための接近箇所14を形成する。接近箇所14は、信号出力面13の一部を、生体接触面12に対して所定の間隔(例えば、2mm)以下となるように接近させたもので、例えば、熱処理で本体部11のスポンジ状の導電性繊維を収縮させて形成することができる。【選択図】図1
