The wearable electrode is an electrode (203) fixed to the garment (21) so as to simultaneously contact the skin of each region from the ventral side to the dorsal side of the left upper body of the wearer (20); And an electrode (204) fixed to the clothes (21) so as to simultaneously contact the skin of each region from the ventral side to the dorsal side of the right upper body. The electrodes (203, 204) are worn such that the wearing position gradually decreases from the ventral side to the dorsal side when the wearer (20) is upright, or from the ventral side to the dorsal side when the wearer (20) is upright It is installed so that the position will gradually rise.ウェアラブル電極は、着用者(20)の左上半身の腹側から背側にかけての各部位の皮膚に同時に接触し得るように衣服(21)に固定された電極(203)と、着用者(20)の右上半身の腹側から背側にかけての各部位の皮膚に同時に接触し得るように衣服(21)に固定された電極(204)とから構成される。電極(203,204)は、着用者(20)が直立の状態で腹側から背側にかけて装着位置が漸次下がるように、あるいは着用者(20)が直立の状態で腹側から背側にかけて装着位置が漸次上がるように設置される。
