PROBLEM TO BE SOLVED: To provide a bioelectrode capable of reducing impedance with a human body, without the need of fixing a shield separately in order to prevent noise of static electricity or the like and without applying conductive cream or the like unlike before.SOLUTION: On a surface on a counter human body side of a substrate 1, a nonwoven fabric 2 is provided. A conductor 3 is provided on a surface on a human body side of the substrate 1. An insulator 4 is provided on a surface on the human body side of the conductor 3. A reception body 6 is provided on a surface on the human body side of the insulator 4. A sponge 8 impregnated with hydrous gel 9 is provided on the human body side of the reception body 6. The sponge 8 and the reception body 6 are attached by a double-sided adhesive tape 7. Earth gel 5 is provided on the surface on the human body side of the conductor 3 at a position different from the insulator 4. Upon use, a cover 10 is detached, the sponge 8 impregnated with the hydrous gel 9 is brought into contact with a prescribed part of the human body, and the insulator 4 and the earth gel 5 are attached to the human body.COPYRIGHT: (C)2014,JPO&INPIT【課題】静電気等のノイズ防止のために別途シールドを固定する必要がなく、かつ、従来と異なり導電性クリームなどを塗らなくても人体とのインピーダンスを小さくすることの可能な生体電極を提供する。【解決手段】基材1の反人体側の面に不織布2が設けられる。基材1の人体側の面に導電体3が設けられる。導電体3の人体側の面に絶縁体4が設けられる。受信体6は、絶縁体4の人体側の面に設けられる。含水ゲル9を染み込ませたスポンジ8は、受信体6の人体側に設けられる。スポンジ8と受信体6との接着は両面接着テープ7が行う。アースゲル5は、導電体3の人体側の面であって絶縁体4とは異なる位置に設けられる。使用の際には、カバー10を取り外し、含水ゲル9の染み込んだスポンジ8を人体の所定部位に接触させ、絶縁体4とアースゲル5を人体に接着する。【選択図】図1
