A electrical stimulation for attachment to grant electrical stimulation to the human body, the first It is held at the electrode and a second state in which the electrodes and spaced apart, the first electrode is positioned on one side surface side of the human torso, to position the second electrode on the other side surface side of the human torso together, and holds the first electrode attachment member having a first electrode holder which is mounted so as to surround the body portion, the third electrode comprising a first electrode pair, the first electrode is located holding the second electrode attachment member having a second electrode holder to be mounted at a position surrounding one of the knee on the side, a fourth electrode formed of the second electrode pair and the second electrode to provide electrical stimulation for attachment, characterized in that a third electrode attachment member having a third electrode holding portion is attached to a position surrounding the other of the knee on the side to be positioned. According to the electrical stimulation attachment, it is possible to simplify the configuration, effects such as muscular hypertrophy and metabolic promotion to impart higher electrical stimulation.人体に電気刺激を付与する電気刺激用装着具であって、第1の電極および第2の電極を離間した状態で保持し、第1の電極を人体の胴部における一方の側面側に位置させ、第2の電極を人体の胴部における他方の側面側に位置させるとともに、胴部を取り囲むように装着される第1の電極保持部を有する第1の電極装着部材と、第1の電極と対になる第3の電極を保持し、第1の電極が位置する側の一方の膝部を取り囲む位置に装着される第2の電極保持部を有する第2の電極装着部材と、第2の電極と対になる第4の電極を保持し、第2の電極が位置する側の他方の膝部を取り囲む位置に装着される第3の電極保持部を有する第3の電極装着部材とを有することを特徴とする電気刺激用装着具を提供する。この電気刺激用装着具によれば、構成を簡略化し、筋肥大や代謝促進等の効果が高い電気刺激を付与することができる。
