PROBLEM TO BE SOLVED: To improve the estimation precision by putting a multi-frequency probe current to an organism every frequency, measuring the probe voltage and current every frequency to determine the electric admittances or electric impedances in zero frequency and infinite frequency, and estimating the weight except bone and fat weight according to a specified expression. ;SOLUTION: A mensuration signal generator 52 outputs a measurement signal 1a changing stepwise in a prescribed sweeping period at a prescribed frequency interval according to the signal generation instruction signal SG from a CPU 10. A multi-frequency probe current 1b is thus carried to a subject. The voltage data Vp is stored in a memory 74 every frequency of the mensuration signal 1a. Electric admittances Y(0), Y(∞) in zero frequency and in infinite frequency are calculated therefrom, and further applied to an expression to estimate the weight except bone and fat weight LEAN. In the expression, H is the statue of the subject, and (a)-(d) are constants. According to this, the estimation can be precisely performed.;COPYRIGHT: (C)2000,JPO
