PROBLEM TO BE SOLVED: To provide an electric characteristic measuring system which can display a physical quantity based on a bioelectrical impedance as an interval estimate value, based on a bioelectrical impedance method. SOLUTION: A measuring signal generator 72 or the like generates a measuring signal, and charges the measuring signals to a subject through surface electrodes Hc and Lc which are conductively attached to surface areas at specified two locations being separated from each other of the subject. An I/V converter 91 or the like measures the current value of the measuring signal which is thrown into the subject. A differential amplifier 81 or the like measures the voltage value which is generated between the surface areas at the specified two locations being separated from each other of the subject. A CPU 3 calculates the bioelectrical impedance between the surface areas of the subject by the current value and the voltage value being respectively measured by the current and voltage measuring means, and calculates the physical amount based on the bioelectrical impedance. In addition, the CPU 3 output-controls the calculated physical quantity as the interval estimate value. |
