PROBLEM TO BE SOLVED: To improve a degree-of-freedom of an installation position of an electrode for detecting a biological signal of a measurement object.SOLUTION: An electrode unit includes: an electrode capable of detecting a biological signal emitted from a measurement object； a penetration part penetrating into a garment worn by the measurement object； and a fixing part arranged on a second surface different from a first surface which contacts the skin of the measurement object of the garment, and detachably fixing the electrode to the garment by sandwiching the electrode and the garment via the penetration part. The electrode or the fixing part is constituted so as to be connected with a cable for delivering a biological signal detected by the electrode to a biological signal measurement device.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】被測定体の生体信号を検出する電極の設置位置の自由度を向上させる。【解決手段】被測定体から発せられる生体信号を検出可能な電極と、被測定体によって着用される衣服を貫通する貫通部と、衣服の被測定体の肌に接触する第１の面とは異なる第２の面に配置され、貫通部を介して、電極と衣服を挟み込むことで、電極を衣服に対して着脱可能に固定する固定部と、を備える電極ユニットである。電極又は固定部は、電極によって検出された生体信号を生体信号測定装置に送出するケーブルを接続可能に構成される。【選択図】図１
