Abstract:
1. A body fat measurement device, comprising: a belt configured to be wrapped around an abdomen of a subject; a plurality of electrodes which are provided on the belt and configured to contact a body surface of the subject; a current applier which passes a predetermined current between a pair of electrodes of the plurality of electrodes; a first measurer which measures a voltage between another pair of electrodes, of the plurality of electrodes, while the current is passed between the pair of electrodes by the current applier; a calculator which calculates an abdominal impedance of the subject on the basis of the voltage measured by the first measurer and calculates an amount of body fat of the subject by using the calculated abdominal impedance; a second measurer which measures a parameter other than the abdominal impedance and outputs a signal indicating the measured parameter to the calculator; a cable in which a first core wire which connects between at least one of the current applier and the pair of electrodes, and the first measurer and the another pair of electrodes, and a second core wire which connects the second measurer and the calculator are provided inside a same insulating coating; and an isolator which can shut off a connection between the second core wire and the calculator, wherein the calculator shuts off the connection between the second core wire and the calculator by the isolator, during measurement of the abdominal impedance, acquires the voltage measured by the first measurer while the connection is shut off, and calculates the abdominal impedance on the basis of the acquired voltage.
