Summary:To provide a biological impedance measurement device which can accurately measure a biological impedance by reducing the influence of noise.SOLUTION: There is provided a biological impedance measurement device 1 which includes at least two electrodes 10, 20 that are arranged on a living body surface 30, measures the first voltage generated when a first external resistor Rg1 is connected in parallel between the two electrodes 10, 20 and the second voltage generated when a second external resistor Rg2 is connected in parallel, and calculates a biological impedance between the two electrodes 10, 20 in a muscle portion 31 under the living body surface 30 on the basis of the voltage ratio of the first voltage to the second voltage, the biological impedance measurement device is driven by a battery 103 in at least the time of measurement of the biological impedance.SELECTED DRAWING: Figure 1 【課題】ノイズの影響を低減して、生体インピーダンスを精度よく測定することができる生体インピーダンス測定装置を提供する。【解決手段】生体表面３０に配置する少なくとも２つの電極１０，２０を有し、２つの電極１０，２０間に、第１の外部抵抗Ｒｇ１を並列接続したときに生じる第１の電圧および第２の外部抵抗Ｒｇ２を並列接続したときに生じる第２の電圧を測定し、前記第１の電圧および前記第２の電圧の電圧比に基づいて、生体表面３０下の筋肉部位３１における２つの電極１０，２０間の生体インピーダンスを算出する生体インピーダンス測定装置１において、少なくとも生体インピーダンスの測定時は、バッテリ１０３で駆動する。【選択図】図１
