The present invention relates to a bioelectrode sensor for self holding. More particularly, the present invention relates to a bioelectrode sensor for self holding which has no bonding layer and pad. A bioelectrode sensor for self holding according to an embodiment of the present invention includes dry electrodes, and electrode pad, a lead line, and bonding grooves. The bonding grooves according to an embodiment of the present invention are formed on a surface of a substrate. According to an embodiment of the present invention, a bonding groove formed on a surface of a substrate is manufactured by an etching method. The dry electrode is electrically connected to the lead line.본 발명은 생체전극 센서에 관한 것으로, 보다 상세하게는 접착층 및 패드 없이 탈부착이 가능한 자기 접합 생체전극 센서에 관한 것이다.
