摘要：
[Problem] Provide a differential amplifier circuit that detects the surface muscle activity potential, and also serves as a detection circuit that determines the close contact of a living body electrode with the body surface, and can determine the body electrode pair even during the period of detecting the surface muscle activity potential. Superficial muscle evaluation system. [Solution] The common mode removal function of a differential amplifier circuit that connects a set of biological electrodes to an inverting input and a non-inverting input and outputs a difference in surface muscle active potentials appearing in a set of biological electrodes, A common-mode test signal is output to a common electrode that is in close contact with the body surface in the middle of a group of biological electrodes, and a common-mode test signal of a predetermined signal strength is output by a differential amplifier circuit, so it is determined that a certain biological electrode is not in close contact with Body surface.[課題] 提供一種將檢測表面肌活動電位的差動放大電路，兼用為判定生物體電極對體表面的密接的檢測電路，即使為檢測表面肌活動電位的期間，亦可判定生物體電極對體表面的密接的肌肉評估系統。[解決手段] 利用將一組生物體電極連接於反轉輸入與非反轉輸入，且輸出在一組生物體電極所出現的表面肌活動電位的差分的差動放大電路的共同模式去除功能，對在一組生物體電極的中間密接於體表面的共同電極輸出共同模式測試信號，且由差動放大電路被輸出預定的信號強度的共同模式測試信號，因此判定某個生物體電極未密接於體表面。
