Problem to be solved: to provide an induction device for an organism electrode for guiding an electrode for a living body which adheres to an organism surface of an optional muscle to an optimum adhesion position based on the position of a neuromuscular junction of an arbitrary muscle and an optional muscle in the living surface.The relative position of the neuromuscular junction of the voluntary muscle and the voluntary muscle to the surface of the organism is detected from the muscle action potential detected in the electromyogram detecting electrode closely connected to the position of the large number of the living surface, and it is adhered to the surface of the voluntary muscle using the relative position information The adhesion position of the electrode for the organism is guided to the optimum position.Diagram【課題】生体表面内の随意筋や随意筋の神経筋接合部の位置をもとに、随意筋の生体表面に密着させる生体用電極を最適な密着位置に誘導する生体用電極の誘導装置を提供する。【解決手段】生体表面の多数の位置に密着させた筋電検出電極において検出される筋活動電位から生体表面に対する随意筋や随意筋の神経筋接合部の相対位置を検出し、その相対位置情報を用いて随意筋の生体表面に密着させる生体用電極の密着位置を最適な位置へ誘導する。【選択図】図4
