PROBLEM TO BE SOLVED: To enhance the presumptive calculating accuracy for the body composition, for example the body water content distribution, the condition of body fat, hematocrit value, or the like. SOLUTION: A signal output circuit 5 feeds a multi-frequency current Ib into the body of a subject, and a current sensing circuit 6 senses the current Ib flowing through the body of a subject, while a voltage sensing circuit 7 senses the voltage Vp between his hands and feet. A CPU 10 measures the bioelectric impedance on the basis of the obtained current Ib and voltage Vb and calculates the extra-cellular fluid resistance and intra-cellular fluid resistance of the body of the subject on the basis of the determined bioelectric impedance. On the basis of the obtained extra-cellular and/or intra-cellular fluid resistance, the amount of extra-cellular fluid, that of intra-cellular fluid, water content of his body, rate of body fat, hematocrit value, or the like are presumptively calculated, and the results are displayed in a display 9. |
