PROBLEM TO BE SOLVED: To achieve both of convenience for a user and measurement accuracy without reducing reliability.SOLUTION: In an electrode for measuring a bioelectric potential, at least a part in contact with a living body comprises: a substrate resin layer which is mainly composed of a prescribed resin material, rubber or elastomer； and conductive particles contained in the substrate resin. The conductive particles comprise: prescribed substrate particles； and a surface treatment region in which at least a part of surfaces of the substrate particles is coated or substituted with a prescribed material.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】信頼性を低下させることなく、使用者の利便性と測定精度とを両立させること。【解決手段】本開示に係る生体電位計測用電極は、少なくとも生体と接する部分が、所定の樹脂材料、ゴム又はエラストマーを主成分とする基材樹脂層と、前記基材樹脂中に含有された導電性粒子と、を備え、前記導電性粒子は、所定の基材粒子と、当該基材粒子の表面の少なくとも一部が所定の材料により被覆又は置換された表面処理領域と、を有する。【選択図】図１
