PROBLEM TO BE SOLVED: To provide an electrode and a device for low frequency electrical stimulation in which electrochemical reaction is not caused even if an electrode surface gets wet, also current concentration to a low resistance part of skin is not caused even if an electrode plane is directly brought into contact with the skin, and further it can be brought into contact with the skin safely and can be used in water, and also DC outflow can be cut off even if a DC is output between the electrodes by mistake.SOLUTION: An electrode for low frequency electrical stimulation is characterized by being constituted of an electrically-conductive electrode 3, an insulator electrode membrane 2 coating a surface of the electrically-conductive electrode 3, an energization line 4 electrically connected to the electrically-conductive electrode 3, and an insulating coating body for coating at least the conducting electrode 3 and the energization line 4 and coating so as to expose a part or all of the insulator electrode membrane 2. Also, a low frequency electrical stimulation device comprises at least one pair of insulator electrodes for the low frequency electrical stimulation, and also can output a rectangular wave of a peak value 4 [V] or more between the electrodes.SELECTED DRAWING: Figure 1【課題】電極表面が濡れていても電気化学反応が起こらず、また、電極面を皮膚に直接当接しても皮膚の低抵抗部への電流集中を起こさず、更に、水中でも安全に皮膚に当接して使用でき、また、誤って直流が電極間に出力されてしまっても、直流の流出を遮断できる低周波電気刺激用の電極及び装置を提供する。【解決手段】導電性電極部3と該導電性電極部3の表面を被覆した絶縁体電極膜2と、該導電性電極部3に電気的に接続された通電ライン4と、前記導電性電極部3と前記通電ライン4とを少なくとも覆うとともに前期絶縁体電極膜2の一部もしくは全部を露出させるように被覆する絶縁性被覆体と、より構成されたことを特徴とする低周波電気刺激用電極である。また、当該低周波電気刺激用絶縁体電極を少なくとも一対具備し、当該電極間に波高値4[V]以上の方形波を出力できる低周波電気刺激装置である。【選択図】図1
