PURPOSE:To carry out the stable measurement which is hardly influenced by the contact resistance and cables by constituting, integrally at least as one body, an electrode part for detecting the living body potential in close contact with a living body and an impedance conversion circuit in which the living body potential detected by the electrode part is converted into the low impedance and outputted. CONSTITUTION:A title living body potential measuring electrode is constituted of an electrode plate 11 for detecting the living body potential in contact with a living body, casing 12 which is formed so as to cover the back surface of the electrode plate 11, impedance converter 13 accommodated in the casing 12, and an output cable 14 for connecting the output of the impedance converter 13 and the input of a measuring device. The living body potential detected by the electrode plate 11 is inputted into the impedance converter 13 through an input cable 15, and the impedance converter 13 outputs the living body potential which is received with high impedance to the measuring device with low impedance through the output cable 14. Accordingly, because of the direct vicinity of a measurement point, the input impedance of the impedance converter can be set high, and since the measuring decice can be connected with low impedance, stable measurement can be carried out. |
