To provide a bioelectrode capable of acquiring a bioelectric signal with high accuracy even in a situation where artifacts are easily taken in a bioelectric signal such as a situation where a body motion is large.A bioelectrode is provided with an electrode layer constituted by a fiber knitted fabric, and the surface roughness (Ra) of the fiber knitted fabric is 40 m or less. Wherein the fiber knitted fabric comprises a conductive fiber and a thermally fusible fiber or a thermally coalesced fiber, and the conductive fiber and the thermally fusible fiber or thermally coalesced fiber are bonded to each other.Selection drawing None【課題】体動が大きい状況など、生体電気信号中にアーチファクトが取り込まれやすい状況においても、生体電気信号を高い精度で取得できる生体電極を提供する。【解決手段】繊維編地により構成された電極層を備えており、前記繊維編地の表面粗さ(Ra)が、40μm以下である、生体電極。前記繊維編地が、導電性繊維と、熱融着繊維または熱合着繊維とを含んでおり、前記導電性繊維と前記熱融着繊維または熱合着繊維とが結合されている生体電極。【選択図】なし
